%N Integers n for which ceiling(n/2)*10^n - ceiling(n/2) is an n-White number.

%C Note that every 1- and 2-digit odd integer appears in the sequence.

%e The number 6 * 10^11 - 6 = 599999999994 is an 11-White number, so the number 11 appears in the sequence.

%Y Cf. A037042, A037043, A037044, A037045.
