Question

A certain business has implemented a new incentive plan whereby an employee earns tokens for every sale they make.

For 1 sale, an employee earns 1 token.
For 2 sales, an employee earns 9 tokens.
For 3 sales, an employee earns 21 tokens.
For 4 sales, an employee earns 37 tokens.

Which recursive equation represents the pattern?

an = an - 1 + 4n

an = an - 1 + 4(n + 1)

an = an - 1 + (n + 4)

an = an - 1 + (n – 4)
