The OEIS Foundation is supported by donations from users of the OEIS and by a grant from the Simons Foundation.

 Please make a donation to keep the OEIS running. We are now in our 56th year. In the past year we added 10000 new sequences and reached almost 9000 citations (which often say "discovered thanks to the OEIS"). Other ways to donate

 A281067 a(1) = 1; a(n) is the smallest natural number such that a(n) > a(n-1), and the name of a(n) in English starts with the letter a(n-1) ends with, and a(n) makes the sequence extendable. 3

 OFFSET 1,2 COMMENTS "a(n) makes the sequence extendable" means the name of a(n) does not end with any of the letters r, x, y and d. LINKS EXAMPLE If a(5) were 90 (ninety, which ends with y), it would make the sequence finite. Therefore, a(5) has to be 91. CROSSREFS Cf. A277971, A277972, A281068.
