Which sequences are geometric? Check all that apply.

Geometric sequences are:

-1, 2.5, - 6.25, 15,625, ...

8, 0.8, 0.08, 0.008, ...

Geometric sequence is a sequence of numbers term after the first term is found by multiplying the previous term by a common ratio - - a fixed, none-zero number.

-1 * - 2.5 = 2.5

2.5 * - 2.5 = - 6.25

-6.25 * - 2.5 = 15.625

8 * 0.10 = 0.8

0.8 * 0.10 = 0.08

0.08 * 0.10 = 0.008
