Question

. a man starts repaying a loan as first installment of rs.100. if he increase the installment by rs.5 every month, what amount will he pay in the 30th installment

Answer 1

We can form a general formula to solve this question.

$t(n) = 100 + (n - 1)5$

T(n) represents amount paid in "n"th month
"n" represents No. of Month.
So, to calculate amount paid in 30th month,

T(30)= 100+ (29×5) = 100+145
T(30)= 245

Hence, he would pay ₹245 in 30th installment.
