Question

I need help with this please! I want someone to go through the steps with me, not tell me the answer. Thanks~! ^_^

Jake has proved that a function, f(x), is a geometric sequence. How did he prove that?

He showed that an explicit formula could be created.

He showed that a recursive formula could be created.

He showed that f(n) ÷ f(n − 1) was a constant ratio.

He showed that f(n) − f(n − 1) was a constant difference.
