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.

The defining characteristic of any arithmetic sequence is called the common difference. It is a constant difference found between any term and the term preceding it.

"She showed that f (n) - f (n-1) was a constant difference."
