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 61st year, we have over 378,000 sequences, and we’ve reached 11,000 citations (which often say “discovered thanks to the OEIS”).

COMMENTS
Two variations are possible: Not requiring monotonicity (i.e., the sequence could go: ZerO, OnE, EighT, TeN, NinE, EighteeN, NineteeN, ...), and imposing the additional constraint that the sequence does not stop right after the chosen number (so "NinetY" would be forbidden and "Ninety-onE" should be used instead). See A227865 for a French and A228442 for a German version using such rules. - M. F. Hasler, Nov 03 2013
