Vincenzo Librandi, Table of n, a(n) for n = 0..200
Index entries for linear recurrences with constant coefficients, signature (10,-16).
FORMULA
a(n) = 8*a(n-1) - 2^n = 10*a(n-1) - 16*a(n-2).
From Mohammad K. Azarian, Jan 02 2009: (Start)
G.f.: 1/(1-2*x) + 1/(1-8*x).
E.g.f.: e^(2*x) + e^(8*x). (End)
