 OFFSET 0,1 LINKS 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 MATHEMATICA Table[6^n + 8^n, {n, 0, 20}] LinearRecurrence[{14, -48}, {2, 14}, 30] (* Harvey P.
