This sounds like my core 2 mathematics from last year, it sounds like a geometric progression. your talking about interest, yes?
3000x1.02^n = 6000
6000/3000 = 2
1.02^n = 2
log (base 1.02) 2 = n
n= 35?
I'm not quite sure if that's right.
Another reply: The exact answer is log(2) / log(1.02) (logarithm in any base, same base for both). Almost exactly 35 years. (1.02 is 1 + 2%). For a quick estimate, divide 70% by the interest rate, in this case, 2% - this gives you 35 years. This is a rough formula, that will fail for higher percentages.
