mcTY-apgp This unit introduces sequences and series, and gives some simple examples of each. It also explores particular types of sequence known. Given the first term and the common difference of an arithmetic sequence find the recursive formula and the three terms in the sequence after the last one given. SOLUTION. The sequence is arithmetic with first term a1 = 50 and common difference The nth term of an arithmetic sequence with first term a1 and common.

In maths, sequence refers to a condition where difference in between the digits in a series in constant. An example of arithmetic sequence is — 1, 3, 5, 7, 9. Are you looking to improve your skills in arithmetic sequence and are in need of help? Well, we are here with our best expert guidance on arithmetic sequence. This easy thought will surely change your working style as you will feel easier to work with arithmetic sequences. Download Arithmetic Sequence Definition It is not the time to look for by chance solution of mathematical expectations as it is time to go for chosen criteria of arithmetical ideas.

Remember the formula: Solve the following problem using the formula. The unknown in the problem is the 20th term in the sequence. This is represented as a Do you understand the solutions to the examples presented? If you do, you may continue reading this module. If you do not, read the discussion and try answering the problems again. Let us try some more problems. Let us analyze the problem.

The following are the given facts in the problem: This means that after 3 months, his wage will be P After 6 months, his wage will be P This means that in 5 years, his wage will increase by P5. Therefore, we have the sequence 30, 35, 40, 45, 50,. You are asked for the 20th term in the given arithmetic sequence. The equation for a20 is: Compare your answers with those found in the Answer Key on page If your answers are wrong, read the parts which are not clear to you again.

If you got them right, congratulations. You did a very good job. Try solving the next problem.

How much would she have saved by the end of the month? What are the values given in the problem? We have 5, 5. What do these numbers form? The numbers form an arithmetic sequence. You are asked for the amount that Analiza would be able to save by 30 September. This is equivalent to the 30th term of the arithmetic sequence 5, 5. Use the 5 steps in applying the formula for finding the nth term in an arithmetic sequence to solve the following.

Find the 28th term in an arithmetic sequence if the 1st term is 20 and the common difference is —5. What is the 17th term in the arithmetic sequence 7, 7. A stack of bricks has 61 bricks in the bottom layer, 58 bricks in the 2nd layer, 55 bricks in the 3rd layer, and 10 bricks in the last layer.

How many bricks are there in the 11th layer? The seats in a theater are arranged so that there are 70 seats in the 1st row, 72 seats in the 2nd row and so on for 30 rows altogether. How many seats are there in the last row?

Once a month, a man puts some money in a cookie jar. During the 1st month he has P How much money was placed in the jar during the last month of the 4th year? Compare your answers with those found in the Answer Key on pages 39 and Continue reading this module. If you got only 4 or below, read Lesson 2 again, then try solving the exercises given again. You will also learn how to apply that process in your daily life. From the series of numbers, find out the following: Is the series an arithmentic sequence?

Do the numbers in the series have a common difference? If yes, what is the common difference or d? What is the first term or a1? Before answering Question 1, first determine if there is a common difference.

You need to have JavaScript enabled in order to access this site.

Let us compute for the common difference by finding the difference between two consecutive numbers. Therefore, the numbers follow an arithmetic sequence. Now, the first term is This is a1. We can now solve for the number of soft drinks that Jaine-Anne can sell in 10 days.

Each of these sums is called an arithmetic series. An arithmetic series is the sum of the 1st n terms of an arithmetic sequence. In the example above, 90, , , , and so on is an example of an arithmetic series.

Do you want to discover a formula for finding the sum of the 1st n terms of an arithmetic sequence? Earlier, we added the terms in the arithmetic sequence and we came up with the following sums: S2 means the sum of the 1st two terms in an arithmetic sequence.

How do you write the sum of the 1st three terms? S3 is the sum of the 1st three terms in an arithmetic sequence. How do you write the sum of the 1st four terms? STEP 2 Determine the 1st term and the common difference in the given sequence.

In the activity that you did, the 1st term and the common difference are given: STEP 3 Find the formula for finding the unknown sum. Now, note that in the activity that you did: We say that: Are your answers the same as those written below? Suppose an is not given.

Let us see how we can do this. Using this in Equation 2, we have: When do we use Equation 2? Equation 2 is used when the 1st term, a1 and the nth term, an are given. When do we use Equation 3? Equation 3 is used when the 1st term a1 and the common difference, d are given. If you cannot follow anymore, read the previous discussion again.

In Example 1, the 1st term and the common difference are given so we can use Equation 3. From Step 3 we then have: To solve this, follow the steps below: STEP 1 Determine what the unknown is and write its arithmetic notation.

In the given problem you are asked to determine the 1st 32 terms in the arithmetic sequence. Thus, you are to solve for S STEP 2 Find out what the given facts in the problem are. The problem has the following given facts: STEP 3 Determine which formula to use, given the first term, a1 and the common difference, d.

Remember, there are two equations or formulas for finding the sum of the first n terms. The first formula: STEP 1 Determine what the given facts are. The 1st and last terms of the sequence are given. In the given problem, you are asked for the 1st 21 terms in the arithmetic sequence. STEP 3 Decide which formula to use for finding the unknown sum given the 1st and last terms. From Step 3, we have: How much money will she have at the end of 12 years?

Here is my analysis. The wife saves P10, during the 1st year, P10, during the 2nd year, P10, during the 3rd year and so on until the 12th year. The 1st term and the common difference of the sequence are given. STEP 3 Decide which formula to use for finding the unknown sum given the 1st term and the common difference. We are given the 1st term and the common difference, so we will use Equation 3.

From Step 3, we will have: Try solving the following by yourself. He sets aside P On the 8th week, he has saved P How much is the pair of shoes?

This means that there is a common difference. STEP 1 Determine the given facts. The 1st and the last terms of the sequence are given. In the given problem, you are being asked for the sum of the 1st eight terms in the arithmetic sequence.

STEP 3 Decide which formula should be used in finding the unknown sum given the 1st and last terms. Compare your answers with those given in the Answer Key on pages STEP 1 Determine what the given facts in the problem are. If the 1st and last terms are given, use Equation 2. If the 1st term and the common difference are given, use Equation 3. STEP 2 Determine what is being asked for in the problem and write this in arithmetic notation. STEP 3 Decide which formula to use in finding the unknown sum based on the given facts or information.

STEP 4 Substitute the given values in the formula and solve for the unknown. Use the four steps you just learned in finding the sum of the 1st n terms in an arithmetic sequence to solve the following: What is the sum of the 1st 11 terms in an arithmetic sequence whose 1st term is —40 and the 11th term is —73? Use the formula Equation 2 or Equation 3 for finding the sum of the 1st n terms in an arithmetic sequence to solve the following problems. A stack of bricks has 61 bricks in the bottom layer, 58 bricks in the 2nd layer, 55 bricks in the 3rd layer and 10 bricks in the last or 18th layer.
