Question

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.

I don't get this at all how can this be a geometric sequence? please help

Answer 15

Close this question.

Answer 16

Remember:
f(n)=arn−1,n∈Z+

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

Answer 17

where did the arn come from
