Question

Jake has proved that a function, fr, is a geometric sequence. How did he prove that?

Answer 1

next time please post the choices

A) He showed that an explicit formula could be created.
B) He showed that a recursive formula could be created.
C) He showed that f(n) ÷ f(n - 1) was a constant ratio.
D) He showed that f(n) - f(n - 1) was a constant difference.

with that being said, recall the definition of a geometric series (a series in which each consecutive term is created by multiplying the previous term by some r)
