Calculate the future value of quarterly payments of $1200 for 5 years, if the rate of interest was 10% compounded quarterly for the first 2 years and will be 9% compounded quarterly for the last 3 years.

I solved for both which i got
aFV= $10483.34
bFV= $16322.67
to get this answer i used this formula: FV=PMT((1+i)^n))1/i
i just don't know what do i do now?

At the end of the first 2 years, the value of the payments up to that point will be
1200 ( 1.025^8  1)/.025 = 10483.339 (you had that)
let's "move" that up to the end of 5 years at the new rate
value = 10483.339(1.0225^12) = 13691.765
Amount of the last 3 years' payments at year 5
= 1200( 1.0225^12  1)/.0225 = 16322.666
so total amount = 16322.666 + 13691.765 = $30 014.43 
Damon, didn't see that you already did this question.
Well, at least we agree down to the last penny, lol
