When working with compounded interest does doubling the time of an investment double the amount of interest earned

the equation for compound interest is

we will see if it doubles or not

if t=1, we get A=P(1+r)

if t=2, we get A=P(1+r)^2

2(P(1+r))=P(1+r)^2 ?

2(1+r)=(1+r)^2 ?

2+r=r^2+2r+1

etc

when r=-1.618 or 0.618, then it doubles, but not when r is different things

not always

so no, it does not always double the amount of interest earned
