2. (General adjustable formula) Let V, be the value of an adjustable-rate loan initiated at period k and states with initial principal of 100 The loan is to be fully paid at period. The interest rate charged each period is the short rate of that period plus a premium p The loan payment for a period is the amount that would be required to amortize the loan at the charged interest rate equally over the remaining periods Write an explicit backward recursion formula for V, as a function of k and s
