Hi,

I want to find what will be left of number X, after 50 reductions of 2% - each time the reference is whats left from the total sum.

I was trying to find a general formula for this but without success.

x - 0.02X - 0.02(x-0.02x) - 0.02(x - 0.02X - 0.02(x-0.02x)) - ..... (N times)

please help me find a formula for N reductions.
