Geometric sequence is a sequence of values where the next term is the product of the previous term multiplied by a fixed amount called common ratio.

Among the choices, I find 2 that are geometric sequences.

C. 3, -12, 48, -192, 768  common ratio is -4

E. 1, 1/2, 1/4, 1/8,1/16 common ratio is 1/2
