Robert Israel, Table of n, a(n) for n = 0..450

FORMULA

From Robert Israel, Jun 07 2018: (Start)

E.g.f.: exp(16*x-81*x^2).

a(n+2)=16*a(n+1)-162*(n+1)*a(n). (End)

MAPLE

f:= gfun:-rectoproc({-162*(x+1)*a(x) + 16*a(x+1)-a(x+2)=0, a(0)=1, a(1)=16}, a(x), remember):

map(f, [$0..50]); # Robert Israel, Jun 07 2018
