For each of the following cases, indicate (a) what interest rate columns and (b) what number of periods you would refer to in looking up the discount rate. (Round percentages to 1 decimal place, e.g. 15.1\%.) (1) In Table 3 (future value of 1): (2) In Table 2 (future value of an annuity of 1 ): Finding present value if discounted for two periods The present value of 1 may also be determined through tables that show the present value of 1 for n periods. In Table3,n is the number of discounting periods involved. The percentages are the periodic interest rates or discount rates. and the 5 -digit decimal numbers in the The following two demonstration problems (Illustrations G.12 and G.13) illustrate how to use Table 3
