 Hints (Greetings from The On-Line Encyclopedia of Integer Sequences!)
 A252707 "Smallest interesting" sequence such that each term has as many digits as the previous term's value. 1
 2, 10, 1000000000 (list; graph; refs; listen; history; text; internal format)
 OFFSET 1,1 COMMENTS Using 2 as the first term yields the "smallest interesting" sequence with this property. Starting with the value 1 yields the sequence 1, 1, 1, ... and starting with 3 yields a sequence that grows faster (3, 100, 10^99, ...). The next term is too large to include. - N. J. A.
