Vincenzo Librandi, Table of n, a(n) for n = 0..10000

Index entries for linear recurrences with constant coefficients, signature (4, -6, 4, -1).

FORMULA

From Chai Wah Wu, Jul 14 2016: (Start)

a(n) = 4*a(n-1) - 6*a(n-2) + 4*a(n-3) - a(n-4) for n > 3.

G.f.: (64*x^3 + 1941*x^2 + 2244*x + 125)/(x - 1)^4. (End)
