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

The defining characteristic of any geometric sequence is the common ratio, which is the constant found when dividing any term by the term preceding it.

C.  He showed that f(n)/(f(n-1) was a constant ratio.
The answer to your question is : C. He showed that f(n) ÷ f(n − 1) was a constant ratio.
