Colin Barker, Table of n, a(n) for n = 0..1000

Index entries for linear recurrences with constant coefficients, signature (11,-50,120,-160,112,-32).

Formula

a(n) = (24*(-8+81*2^n)+1671*2^(1+n)*n+803*2^n*n^2+27*2^(1+n)*n^3+2^n*n^4) / 192 for n>0. - Colin Barker, May 27 2015

G.f.: -(260*x^6-996*x^5+1488*x^4-1088*x^3+388*x^2-52*x-1) / ((x-1)*(2*x-1)^5). - Colin Barker, May 27 2015
