Let a, denote the amount owed at the end of the nth month. The payments start the first month and are due the last day of every month. a. Give a recurrence relation for a,,. Don't forget the basis (also called the initial conditions). b. Suppose the borrower would like a lower monthly payment. How large does the monthly payment need to be to ensure that the amount owed decreases every month? 6. Suppose someone takes out a home improvement loan for $30,000.
