If you earn $3500 over 10 years on an investment that pays 5.3% compounded annually what was the principal amount you started with

Amount , A= $3500

Time , t= 3 years

rate , r= 5.3% = 0.053

Compounded annually , n= 1

The formula we use here is

Now let's plug the values

Divide both sides by 1.67603742459

We get

P = $2088.258859

It means started with approx $2088.26

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18

uhhh idk u yolo?
