The sequence of values will be:

A1 = -2 + 6 = 4

A2 = -2 + 6(2) = -2 + 12 = 10 (= 4 + 6)

A3 = -2 + 6(3) = -2 + 18 = 16 (= 10 + 6)

A4 = -2 + 6(4) = -2 + 24 = 22 (= 16 + 6)

and so on...

From those values, you can see that each "An" is equal to the previous value, plus 6.

In recursive notation, the equation would be:

An = An-1 + 6
