This is a geometric sequence

#### Explanation:

For an arithmetic sequence you have to add/subtract the same number to each successive term.

For example if the first term is 2 and you add 2 to each term you get

2, 4, 6, 8........etc

With 2,4,8,16 you are multiplying each successive term by 2 to get

2 * 2 = 4

4 * 2 = 8

8 * 2 = 16 etc

geometric sequences can also involve successive divisions
