The sequence is arithmetic.


An arithmetic sequence has a common difference, meaning you use addition or subtraction to get from term to term, and each term in the sequence is an equal distance apart.

A geometric sequence has a common ratio, meaning that you use multiplication or division to get from term to term.

If you look at this sequence:
14-2 = 12
12-2 = 10
10-2 = 8
8 -2 = 4

Because you are subtracting 2 each time, 2 is the common difference, and the sequence is arithmetic.
