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.: (125 + 2244*x + 1941*x^2 + 64*x^3)/(1 - x)^4. (End)
E.g.f.: (125 + 2619*x + 3402*x^2 + 729*x^3)*exp(x). - G. C. Greubel, Jan 06 2023
