One example from the books states:

with $\displaystyle a0=2$ and $\displaystyle a1=7 $

I feel that if I had the correct procedures down I could do the work. Any help please and thanks.

This then translates into problems of higher degree. Such as:

$\displaystyle an=6an-1 - 11an-2 + 6an-3 $

Initial conditions $\displaystyle a0=2, a1=5, a2=15 $
