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

Index entries for linear recurrences with constant coefficients, signature (14,-48).

FORMULA

From Mohammad K. Azarian, Jan 11 2009: (Start)

G.f.: 1/(1-6*x) + 1/(1-8*x).

E.g.f.: e^(6*x) + e^(8*x). (End)

a(n) = 14*a(n-1) - 48*a(n-2) with a(0)=2, a(1)=14. - Vincenzo Librandi, Jul 21 2010
