FORMULA

A104463(n)=s(n)+Floor(s(n)/2), where s(n)=A072756(n).

a(n)=A072757(n-2), n>1. [From R. J. Mathar, Aug 28 2008]

EXAMPLE

The sequences a(n)=A072756(n) and b(n)=A104463(n) are jointly defined:

a(n) = least positive integer not a(k) + Floor(a(k)/2) for k<n. Thus

a(0)=0, b(0)=0, a(1)=1, b(1)=1, a(2)=2, b(2)=3, a(3)=4, b(4)=6,...

CROSSREFS
