LINKS

Table of n, a(n) for n=0..80.

Index entries for linear recurrences with constant coefficients, signature (0,1).

FORMULA

a(n) = -3/2(-1)^n+13/2. a(n) = 8*(n mod 2)+5*[(n+1) mod 2]. - Paolo P. Lava, Oct 20 2006

a(n) = a(n-2) for n > 1; a(0) = 5, a(1) = 8. G.f.: (5+8*x)/((1-x)*(1+x)).  - Vincenzo Librandi, Aug 01 2010

a(n) = 3*(n mod 2) + 5. - Wesley Ivan Hurt, Jun 14 2014
