Vincenzo Librandi, Table of n, a(n) for n = 0..300

Index entries for linear recurrences with constant coefficients, signature (32, -364, 1728, -2880).

Formula

a(n)=(12^(n+3)-2*10^(n+3)+2*6^(n+3)-4^(n+3))/96. [Yahia Kahloune, Jun 11 2013]

a(0)=1, a(1)=32, a(2)=660, a(3)=11200, a(n)=32*a(n-1)-364*a(n-2)+ 1728*a(n-3)- 2880*a(n-4). - Harvey P. Dale, Aug 15 2013
