Hi,
a person has deposited rs 25,000 in an investment which yields 14% simple interest annually.
do these amounts (principal+interest) form an arithmatic progression?
if so, determine the amount of inverstment after 20 years
In General 
A = Accumulated Amount
P= principal = 25,000
r= annual rate = .14
n= periods per year = 1
t= years = 20
= $343,587.25
