If you deposit $100 in one year, $200 in the second year, and $300 in the third year, how much will you have at the end of three years? How much of this is interesting? How much will you have at the end of five years if you dont add additional amounts? Assume a 4% interest rate throughout. We will calculate the future value of each amount in three years. Notice that the $100 earns interest for two years, and the $200 earns interest for one year. The final $300 earns no interest. The future values are thus:
