Colin Barker, Table of n, a(n) for n = 1..1000
Index entries for linear recurrences with constant coefficients, signature (0,0,6,0,0,-5).
FORMULA
From Colin Barker, Mar 23 2017: (Start)
G.f.: x*(3 + 5*x + 8*x^2 + 22*x^3 - 25*x^4 - 3*x^5) / ((1 - x)*(1 + x + x^2)*(1 - 5*x^3)).
a(n) = 6*a(n-3) - 5*a(n-6) for n>6.
(End)
PROG
(PARI) Vec(x*(3 + 5*x + 8*x^2 + 22*x^3 - 25*x^4 - 3*x^5) / ((1 - x)*(1 + x + x^2)*(1 - 5*x^3)) + O(x^60)) \\ Colin Barker, Mar 23 2017
