Polynomials of Fibonacci numbers
Problem 435
Published on Saturday, 7th September 2013, 04:00 pm; Solved by 97The Fibonacci numbers {fn, n
0} are defined recursively as fn = fn-1 + fn-2 with base cases f0 = 0 and f1 = 1.
Define the polynomials {Fn, n
0} as Fn(x) =
fixi for 0
i
n.
For example, F7(x) = x + x2 + 2x3 + 3x4 + 5x5 + 8x6 + 13x7, and F7(11) = 268357683.
Let n = 1015. Find the sum [
0
x
100 Fn(x)] mod 1307674368000 (= 15!).
