Vincenzo Librandi, Table of n, a(n) for n = 1..100
Index entries for linear recurrences with constant coefficients, signature (11,-10).
FORMULA
From Vincenzo Librandi, Aug 24 2014: (Start)
G.f.: 8*x*(3 + 60*x)/((1 - x)*(1 - 10*x)).
a(n) = 11*a(n-1) - 10*a(n-2). (End)
a(n) = 10*a(n-1) + 504. - Robert Israel, Aug 24 2014
From Elmo R. Oliveira, Dec 03 2025: (Start)
E.g.f.: 8*(6 - 7*exp(x) + exp(10*x)).
