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.
