Question

***RECURSIVE EQUATION***


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 6 tokens.
For 3 sales, an employee earns 12 tokens.
For 4 sales, an employee earns 19 tokens.

Which recursive equation represents the pattern?

an = an - 1 + 3n + 1

an = an - 1 + 3(n + 1)

an = an - 1 + (n + 3)

an = an - 1 + (n – 3)

Answer 1

add 5, add6, add7

Answer 2

a2 = 1 + 5
a3 = 1 + 5 + 6
a4 = 1 + 5 + 6 + 7

Answer 3

an = an-1 + (n + 3) maybe

a2 = 1 + (5)
a3 = 6 + (6)
a4 = 12 + (7)

yeah
