Vincenzo Librandi, Table of n, a(n) for n = 0..700

Index entries for linear recurrences with constant coefficients, signature (24).

Formula

a(n) = A067417(n+7,7).

a(n) = 10*(3*8)^(n-1), n >= 1, a(0)=1.

G.f.: (1-14*x)/(1-24*x).

From Elmo R. Oliveira, Jun 07 2026: (Start)

a(n) = 24*a(n-1) for n > 1.

E.g.f.: (7 + 5*exp(24*x))/12. (End)
