i know how the basic geometric sequence system works, but what if i want to subtract a fixed amount every
For example if i start with $5000 (a1) and is multiplied by 1.05 (5% / r) every day for 20 days (n) I would have $13,267. But what would I have if $20 dollars was subtracted from the total made every day? what's the equation?
for example the first day i would have made 5% or $250 + $5000= 5,250 the first day, but because of the subtraction of $20 every day i would only have made $230 or a total of $5,230 that day? do i make sense?
Sn = [a1(1 - rn)]/(1 - r)
