Chapter 12: Q 81. (page 1184)

In the following exercises, determine if the sequence is arithmetic and if so, indicate the common difference.
$8, 5, 2, - 1, - 4, - 7, \dots$

Short Answer

Expert verified

The value of d is -3.

Step by step solution

Step 1. Given Information.

Consider the given information.

$8, 5, 2, - 1, - 4, - 7, \dots$

Step 2. Find the consecutive difference of the sequence.

Find the difference between the consecutive terms.

$\begin{array}{rcl} 5 - 8 & = & - 3 \\ 2 - 5 & = & - 3 \\ - 1 - 2 & = & - 3 \\ - 4 - (- 1) & = & - 3 \\ - 7 - (- 4) & = & - 3 \end{array}$

Since the common difference is the same.
The value of the common difference is $d = - 3$ .

Step 3. Conclusion.

The sequence is an arithmetic sequence and the common difference is d= -3.
