Question
**Compound Interest:**

Suppose a certain amount of money is deposited in an account paying 4% annual interest compounded quarterly. For each positive integer \( n \), let \( R_n \) be the amount on deposit at the end of the \( n \)th quarter, assuming no additional deposits or withdrawals, and let \( R_0 \) be the initial amount deposited.

a. Find a recurrence relation for \( R_0, R_1, R_2, \ldots \). Justify your answer.

b. If \( R_0 = \$5,000 \), find the amount of money on deposit at the end of one year.

c. Find the APY for the account.
