Given an infinite sequence of numbers $<a_0, a_1, a_2, a_3, . . .>$, the (ordinary) generating function for the sequence is defined to be the power series: $A(x) = \sum_{i=0}^{\infty}a_ix^i = a_0 + a_1x + a_2x^2 + a_3x^3 + . . .$ Consider ... from books as well (I recommend Principles and Techniques in Combinatorics by Chen Chuan Chong) and of course, practice the questions (a lot of them !!))
