Colin Barker, Table of n, a(n) for n = 1..1000
Index entries for linear recurrences with constant coefficients, signature (5,-3,-5,7,-1).
FORMULA
From Colin Barker, Jan 16 2019: (Start)
G.f.: x^2*(1 - x)^2 / (1 - 5*x + 3*x^2 + 5*x^3 - 7*x^4 + x^5).
a(n) = 5*a(n-1) - 3*a(n-2) - 5*a(n-3) + 7*a(n-4) - a(n-5) for n>5.
(End)
