Table of n, a(n) for n=0..11.

Index entries for linear recurrences with constant coefficients, signature (111,-1110,1000)

FORMULA

From Chai Wah Wu, May 30 2016: (Start)

a(n) = 111*a(n-1) - 1110*a(n-2) + 1000*a(n-3) for n > 2.

G.f.: (1510*x^2 - 626*x + 7)/((1 - x)*(1 - 10*x)*(1 - 100*x)). (End)

E.g.f.: (1 + 5*exp(9*x) + exp(99*x))*exp(x). - Ilya Gutkovskiy, May 30 2016
