Paolo Xausa, Table of n, a(n) for n = 0..500
Index entries for linear recurrences with constant coefficients, signature (20,-96).
FORMULA
a(n) = 3*12^n - 2*8^n. - Bruno Berselli, Feb 09 2011
a(n) = 12*a(n-1) + 8^n, a(0)=1. - Vincenzo Librandi, Feb 09 2011
a(n) = 20*a(n-1) - 96*a(n-2), a(0)=1, a(1)=20. - Vincenzo Librandi, Feb 09 2011
