Year-end appeal: Please make a donation to the OEIS Foundation to support ongoing development and maintenance of the OEIS. We are now in our 56th year, we are closing in on 350,000 sequences, and we’ve crossed 9,700 citations (which often say “discovered thanks to the OEIS”).

%N a(1) = 11; for n >= 1, a(n+1) is obtained by replacing the k-th digit of a(n) with the sum of all the less significant digits starting from the k-th digit.

%e After 211 the next term is obtained by replacing 2 with 2+1+1, 1 by 1+1 and retaining the least significant digit and it is 421.

%Y Cf. A110403.
