This problem is a basic one from finance/economics about obtaining the Present Value; but the math is general

to any field.

How is the value 32,097 obtained?

Is it to do with sum to infinity?

$\displaystyle

PV=20,000.\sum_{i=0}^{infinity}\frac{1}{(1+0.05)^{ 20i}}=32,097

$

I haven't given any context (just a word problem). If needed I will provide.

I need help with this; any help is really appreciated!

thanks
