Table of n, a(n) for n=0..15.

Index entries for linear recurrences with constant coefficients, signature (30, -299, 1062, -792).

FORMULA

a(n) = (25*12^(n+3) - 33*11^(n+3) + 11*6^(n+3) - 3)/1650. [Yahia Kahloune, Jun 28 2013]

a(0)=1, a(1)=30, a(2)=601, a(3)=10122, a(n)=30*a(n-1)-299*a(n-2)+ 1062*a(n-3)- 792*a(n-4). - Harvey P. Dale, Nov 20 2013
