Question

4.The sequence corresponding to the generating function x(1-x)...
5. Solution of the recurrence relation a, = 24-1 +1 with ap = 0 is

Answer 1

Answer:

"To find the generating function for a sequence means to find a closed form formula for f(x), one that has no ellipses. (for all x less than 1 in absolute value). Problem: Suppose f(x) is the generating function for a and g(x) is the generating function for b."
