Question

Fiona has proved that a function, f(x), is an arithmetic sequence. How did she prove that?

She showed that an explicit formula could be created.
She showed that a recursive formula could be created.
She showed that f(n) ÷ f(n − 1) was a constant ratio.
She showed that f(n) − f(n − 1) was a constant difference.

Answer 1

what is an arithmetic sequence?

Answer 2

@PaxPolaris its a sequence with the difference between two consecutive terms constant?

Answer 3

I think its D

Answer 4

\[\Huge \checkmark\]

Answer 5
