Vincenzo Librandi, Table of n, a(n) for n = 0..1000
Index entries for linear recurrences with constant coefficients, signature (7,-6).
FORMULA
a(n) = 6*a(n-1) + 1.
a(n) = 7*a(n-1) - 6*a(n-2), n > 1.
G.f.: (2-x)/((6*x-1)*(x-1)). - R. J. Mathar, Oct 31 2011
E.g.f.: exp(x)*(11*exp(5*x) - 1)/5. - Elmo R. Oliveira, Aug 14 2024
