Question

What kind of sequence is this?
-122, -102, -82, -62

Answer 1

arithmetic

Explanation:

First, we look for a common difference.

-102 - (-122) = -102 + 122 = 20

-82 - (-102) = -82 + 102 = 20

-62 - (-82) = -62 + 82 = 20

There is a common difference, and it is 20.

Since the sequence has a common difference, it is an arithmetic sequence.
