# Quick question on how to solve a problem

It has been way to long since I thought about this kind of math. So I was hoping someone here could help.
My question is, How do I figure out 100 * .13 to start and then take that answer and keep multiplying it by .13 and adding that to your previous answer. As in 100 than 113 then 128 (rounding) ...... I want to see what the value would be on the 125th time doing that.

Thank you

Thank you
 100*(1+0.13)^125=431325798.9

Thank you. I figured it was something like that but just could not put it all together. Thank you again.
