Annuity

What formula do I use to solve the question below?

Suppose your parents decide to give you $10,000 to be put in a college trust fund that will be paid in equally quarterly installments over a 5 year period. If you deposit the money into an account paying 1.5% per quarter, how much are the quarterly payments (Assume the account will have a zero balance at the end of period. Do I use: Sn=a((1+i)ⁿ-1)/(1+i)-1

Or

Sn=(a(1+i))((1/(1+i))ⁿ-1)/(1/(1+i))-1
