Prameela deposited Rs.1000 at compound interest of the rate of 10% perannum. The amount at the end of first year, second year, third year....From an A.P. Justify your answer.7,

Answer»

Given,

compound interest=1000

interest=10%per annum

by arithmetic progression,

P (1+r/100)^n

first year=1000 (1+10/100)^1

second year=1000 (1+10/100)^2

third year=1000 (1+10/100)^3

There fore the C. D common difference between three years is different.

so,it is not in A.P
