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. Sloane, Jun 20 2017
