Recall that the Fibonacci and Lucas sequences Fn and Ln are (0, 1, 1, 2, . . . ) and (2, 1, 3, 4, . . . ), respectively. Given that x0 = x1 for the sequence xn in part (d), show that the ratio xn/(Fn + Ln) does not depend on n. where part (d) gives xn = xn?1 + xn?2 where n >= ?? 2. Solution Sequence in part (d) is given by (x0, x0, 2x0, 3x0, 5x0,8x0,....) = x0(1,1,2,3,5,8,....) Fn + Ln = (2,2,4,6,10,....) = 2(1,1,2,3,5,8,....) So clearly if we divide the nth term of xn and Fn+Ln then we get xn/(Fn+Ln) = x0/2 which does not depend on n.
