Find a simple closed formula for the ordinary generating function of the sequence given by
{a[itex]_{n}[/itex]]}n>=0 when a[itex]_{n}[/itex] is given by
a[itex]_{n}[/itex] = 6 * 5^n - 5 * 3^n.
My question is how do you find the recurrence relation a[itex]_{n}[/itex] = 6 * 5^n - 5 * 3^n.
I don't know were to start.
