Which of the following is an arithmetic sequence

C

Step-by-step explanation:

For it be an arithmetic sequence it must either be going up by the same number each time or down by the same number each time.

Lets look at the choices:

A. From 2 to 3 that went up by 1. But from 3 to 7, that doesn't continue to go up by 1. So this sequence is not arithmetic.

B. From 2 to 4, that went up by 2. But from 4 to 16, that doesn't continue to go up by 2. So this sequence is not arithmetic.

C. From 3 to 0, that goes down by 3. From 0 to -3, that goes down by 3. From -3 to -6, thar goes down by 3. This sequence is arithmetic.
