Question: For n ¥ 1, let tn count the number of spanning trees for the fan on n + 1 vertices. The fan for n =

For n ‰¥ 1, let tn count the number of spanning trees for the fan on n + 1 vertices. The fan for n = 4 is shown in Fig. 12.53.

(a) Show that tn+1 = tn + ˆ‘nl=0 tl, where n ‰¥ 1 and t0 = 1.
(b) For n ‰¥ 2, show that tn+1 = 3tn - tn-1.
(c) Solve the recurrence relation in part (b) and show that for n ‰¥ 1, tn = F2n, the 2nth Fibonacci number.
