# Geometric sequences watch

1. A person wants to borrow £100000, intending to pay back a fixed sum £C at the end of each year, so that after 25 years he has completely payed off the debt. Assuming a steady interest rate of 4% per year, explain why

Calculate C

I really shouldnt be working this late, I can't even get started.

Any help guys?
2. a= 1/1.04

r= 1/1.04

n=25

s= (a(r^n - 1))/r-1

100000/ans = c

at least that should be the second part.
