Web4.1 Linear Recurrence Relations The general theory of linear recurrences is analogous to that of linear differential equations. Definition 4.1. A sequence (xn)¥ n=1 satisfies a linear recurrence relation of order r 2N if there exist a 0,. . ., ar, f with a 0, ar 6 0 such that 8n 2N, arxn+r + a r 1x n+r + + a 0xn = f The definition is ... WebSolving a Recurrence Since we know that 1/(1-ax)=1+ax+a2x2+..., we have G(x) = 2(1+3x+32x2+...). Therefore, a sequence solving the recurrence is given by (2,2x3,2x32,...)=(2x3k)k>=0 15 Fibonacci Numbers (1) The Fibonacci numbers satisfy the recurrence: f 0=0 f 1=1 f n= f n1+ f n2for n 2 16 Fibonacci Numbers (2)
