You have a loan outstanding. It requires making $5$ annual payments at the end of the next $5$ years of $ $9,000$ each. Your bank has offered to allow you to skip making the next $4$ payments in lieu of making one large payment at the end of the$$ loan's term in $5$ years. If the interest rate on the loan is $8\mathrm{.}21\%,$ what final payment will the bank require you to make so that it is indifferent between the two forms of$$ payment?
