A 5 -year annuity has a series of payments 1,2,3,2,1 with the first payment made at time t=0 and each subsequent payment occurring one year later than the previous. The present value (i.e. value at time 0 ) of this annuity is 8.41 using an effective annual interest rate of i. A 6 -year annuity has a series of payments 1 , 2, 3, 3, 2, 1 with the first payment made at time t=0 and each subsequent payment occurring one year later than the previous. Find the present value (i.e. value at time 0 ) of the 6 -year annuity at the interest rate
