Using Excel:
FV = 10 * (1.045)^5 = $12.46

The future value for a continuously compounded rate is given by equation (7.15). The rate (r) is the continuously compounded rate, which is 9 percent or .09. The time T in the formula is 2.50. The fu- ture value is $12.52.
FV = 10 x e rT
= 10 x e 0.09x2.5 = $12.52
Using Excel function for ex:
FV = exp(9% * 2.5) = $12.52
7.18
The arithmetic average is 1.73 percent (monthly). The geometric aver- age is 1.64 percent. Note that a dollar invested during that year would have grown to $1.216. If the arithmetic average is com- pounded for a year, the future value is $1.228. However, if the geo- metric average is compounded for a year, the future value matches the actual experience.
