Table of n, a(n) for n=1..80.

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

FORMULA

a(n)=A158606(2n-1)+A158606(2n).

a(n)=(1/2)*{(n mod 5)+[(n+1) mod 5]+5*[(n+2) mod 5]+[(n+3) mod 5]+[(n+4) mod 5]}, with n>=0 [From Paolo P. Lava, Mar 27 2009]

G.f.: -x*(9+11*x+13*x^2+5*x^3+7*x^4)/((x-1)*(1+x+x^2+x^3+x^4)). - R. J. Mathar, Apr 08 2009
