%N A184586 a(n) = floor((n-1/2)*r), where r=sqrt(5); complement of A184587.
%C A184586 r = sqrt(5) and s = (5+sqrt(5))/4 form a Beatty pair. This yields the pair of complementary homogeneous Beatty sequences A022839 and A108598. From a theorem of Thoralf Skolem follows that (a(n)) and A184587 are complementary inhomogeneous Beatty sequences. - _Michel Dekking_, Sep 08 2017
