Let f ( x) denote the generating function for the sequence a k, then we get f ( x) = k 0 a k x k. Take the first equation, then multiply each term by x k. a k x k = a k 1 x k + 2 a k 2 + 2 k x k. And sum each term from 2 since it's a 2-order recurrence relation. A sequence (an) can be viewed as a function f from Recurrences, or recurrence relations, are equations that define sequences of values using recursion and initial values. Example 5.1.6.
