%N a(n) = largest number greater than a(n-1) such that the first n terms of the sequence contain a total of a(n) base-10 digits.

%e a(1) = 1, the only possible first term in base 10. a(9) = 10, the largest possible 9th term (the other possibility is 9) such that the first 9 terms of the sequence contain a total of a(n) base-10 digits.
