Jake has proven that a function, f(x), is a geometric sequence. How did he prove that?
- He showed that an explicit formula can 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
I'm not so sure on my answer. If its wrong, could someone explain to me how to do the problem, I'm very confused. Thank you!
