I am having a sort of brainfreeze or cannot express the mathematical formula for the following:
I have a Natural Number X and I want to reduce it by a Percentage e.g 4% Y times that after Y iterations I get a X < 1. What is the mathematical formula for it and how to calulcate the iterations?
Y1=X*0,96
Y2=Y1*0,94 etc.etc.
Something like f(x) = x*09 f(x) = y < 1
The idea behind it is to calculate an investment sum which by receiving a yearly dividen should be close to zero , meaning the initial investment has already been returned.
