Sinking Fund Payment (Compounding) Formula

Hi! Can someone please help explain the logic and reasoning behind this formula?

Example:

An apartment complex’s parking lot needs to be resurfaced 3 years from now with an estimated cost of $50,000. How much must be invested at the end of each month for 3 years into an account earning 10% annual rate to have $50,000 at end of year 3?

Answer:

Monthly payment is $1,196.69 

What is the logic behind this following formula for calculating sinking fund payments?

Payment per period = Future value * (rate per period / [(1 + rate per period)^number of periods - 1 )]
