%N a(n) is smallest number greater than a(n-1) such that the sequence contains a total of a(n) base 10 digits + commas through n terms (assuming one comma between each pair of terms).
%C The comma after a term is not counted as part of that term.
%e a(1)=1, the only possible initial term in base 10. a(5)=9, the smallest possible number (the other candidate is 10) such that the sequence after 5 terms would contain a(n) base 10 digits + commas.
