Index entries for linear recurrences with constant coefficients, signature (18, -138, 616, -1815, 3762, -5676, 6336, -5247, 3190, -1386, 408, -73, 6).
FORMULA
a(n) = 18*a(n-1) - 138*a(n-2) + 616*a(n-3) - 1815*a(n-4) + 3762*a(n-5) - 5676*a(n-6) + 6336*a(n-7) - 5247*a(n-8) + 3190*a(n-9) - 1386*a(n-10) + 408*a(n-11) - 73*a(n-12) + 6*a(n-13). - Wesley Ivan Hurt, Mar 17 2023
