%N A098727 Consider the sequence {b(n), n >= 1} of digits of the natural (or counting) 
               numbers: 1 2 3 4 5 6 7 8 9 1 0 1 1 1 2 1 3 1 4 1 5 1 6 1 7 1 8 1 
               9 2 0... (A007376); a(n) = b(n) + n.
%C A098727 Add each digit of the counting numbers to its rank.
%e A098727 The sequence of digits of the counting numbers is
%e A098727 1 2 3 4 5 6 7 8 9 1 0 1 1 1 2 1 3 1 4 1 5 1 6 1 7 1 8 1 9 2 0...
%e A098727 The 15th term, for instance, is a 2. Thus 2+15=17 is the 15th term of 
               this sequence.
