Vincenzo Librandi, Table of n, a(n) for n = 0..900
Index entries for linear recurrences with constant coefficients, signature (14,-13).
FORMULA
a(n) = (5*13^n + 1)/6.
G.f.: (1-3*x)/((1-x)*(1-13*x)).
E.g.f.: (5*exp(13*x) + exp(x))/6.
a(n) = 13*a(n-1) - 2; a(n) = 14*a(n-1) - 13*a(n-2). - Vincenzo Librandi, Nov 11 2011
