(Greetings from The On-Line Encyclopedia of Integer Sequences!)
A259921 a(n) is the smallest positive integer > a(n-1) with exactly n letters when written in Spanish. 0

COMMENTS

a(6) = 15 = "quince" (6 letters); 4 = "cuatro" also has 6 letters but is smaller than 5 = a(5) and this sequence is strictly increasing.

Spaces are not counted, so, e.g., "ciento tres" and "doscientos cuatro" are treated as a 10-letter word and a 16-letter word, respectively.
