1. What is the future value of series of $15,600 quarterly payments received at the end of each quarter for the next 7 years if it is invested at an annual rate of return of 7.5% compounded quarterly?

Annuity= 15600

I= 1.875% (7.5% / 4)

n= 28 ( 7*4)

FV= 15600 x [((1+1.875%) ^28 - 1) / 1.875%

= $567,641.26

1. Repeat above question for annuity due? (payments received at the beginning of each quarter). ***I need this part answered****

Thank you
