Alois P. Heinz, Table of n, a(n) for n = 0..1000

Index entries for linear recurrences with constant coefficients, signature (15,-85,225,-274,120).

Formula

a(n) = Sum_{k=1..5} A066633(5,k) * k^n.

a(n) = 12 + 4*2^n + 2*3^n + 4^n + 5^n.

G.f.: -(1814*x^4-2543*x^3+1262*x^2-265*x+20) / ((x-1) *(2*x-1) *(3*x-1) *(4*x-1) *(5*x-1)).

Maple

a:= n-> 12+4*2^n+2*3^n+4^n+5^n:
seq(a(n), n=0..30);
