Question

NEED HELP ASP Find the common difference of the arithmetic sequence -8, -15, -22, ...

Answer 1

-7

Explanation:

To find the differences in a sequence, subtract the term before:

-15 -(-8) = -7

-22 -(-15) = -7

These differences are the same, so constitute the "common" difference.

The common difference of the sequence is -7.
