You are thinking about buying a piece of art that costs $20,000. The art dealer is proposing the following deal: He will lend you the money, and you will repay the loan by making the same payment every two years for the next 10 years (i.e.. a total of 5 payments). If the interest rate is 5% per year, how much will you have to pay every two years?

I NEED an Excel function (or equation or table) for this problem
