Table of n, a(n) for n=0..19.

Index entries for linear recurrences with constant coefficients, signature (12,-35,24).

FORMULA

From Mohammad K. Azarian, Dec 26 2008: (Start)

G.f.: 1/(1-x) + 1/(1-3*x) + 1/(1-8*x).

E.g.f.: e^x + e^(3*x) + e^(8*x). (End)

a(n) = 11*a(n-1) - 24*a(n-2) + 14 with a(0)=3, a(1)=12. - Vincenzo Librandi, Jul 21 2010
