Chapter 12: Q 135. (page 1198)

In the exercise, determine if the sequence is arithmetic, geometric or neither. If arithmetic, indicate the common difference. If geometric, indicate the common ratio.
$- 7, - 2, 3, 8, 13, 18, . . .$

Short Answer

Expert verified

The sequence is arithmetic with common difference equal to $5$ .

Step by step solution

Step 1. Given information

The sequence is $- 7, - 2, 3, 8, 13, 18, . . .$

Step 2. Determine if each sequence is arithmetic, geometric or neither.

Consider the sequence $- 7, - 2, 3, 8, 13, 18, . . .$

$\begin{array}{rcl} - 2 + 7 & = & 5 \\ 3 + 2 & = & 5 \\ 8 - 3 & = & 5 \\ 13 - 8 & = & 5 \\ 18 - 13 & = & 5 \end{array}$

So, the sequence is arithmetic with common difference equal to $5$ .
