An arithmetic sequence always has a common difference, or d, which is the same difference between each term and the one preceding it.

-3--6=0--3=3-0=3

So each term is 3 more than the previous term so this is an arithmetic sequence.

Geometric sequences have a common ratio, where each term divided by the previous term is constant.

If there is no common difference or common ratio, a sequence is neither.
