Asked by Kathy,
I'm having a problem with this warm-up. I know it's recirsive formula, but I have no idea how to correctly find the first five terms. a1= 3, an = an - 1 +2(n-2), n is greater or equal to 2.

just plug in successive values for n
a1 = 3
a2 = 3 + 2(2-2) = 3
a3 = 3 + 2(3-2) = 5
a4 = 5 + 2(4-2) = 9
and so on
a1 = 3
a2 = 3 + 2(2-2) = 3
a3 = 3 + 2(3-2) = 5
a4 = 5 + 2(4-2) = 9
and so on
