 OFFSET 0,2 LINKS Vincenzo Librandi, Table of n, a(n) for n = 0..900 Index entries for linear recurrences with constant coefficients, signature (12,-11). FORMULA a(n) = (4*11^n + 1)/5. G.f.: (1-3*x)/((1-x)*(1-11*x)). E.g.f.: (4*exp(11*x) + exp(x))/5. a(n) = 11*a(n-1) - 2, a(n) = 12*a(n-1) - 11*a(n-2). - Vincenzo Librandi, Nov 10 2011 MATHEMATICA LinearRecurrence[{12, -11}, {1, 9}, 30] (* Harvey P.
