For example if a=$100,r=5%,and n=4 years,then the growth =100*(1+0.05)^4,which is approximately $121.55. Banks sometims offer investments with increasing interest rates, e.g.4% in the first year,4% in the second year, 5% in third year, 7% in fourth year. For an investment of $100, the growth would be 100*1.04*1.04*1.05*1.07,which is approximately$121.52 .

The functionshould be called growth used as follows: |
