Table of n, a(n) for n=1..14.

Example

a(1) = 100 because "cieN" has an N as its last letter (i.e., 1st, counting from the end) and is the smallest such number;
a(2) = 1 because 1 is the smallest number whose name in Spanish ("uNo") has an N as its next-to-last letter (i.e., 2nd, counting from the end);
Similarly, a(3) = 5 ("ciNco"), a(4) = 100000 ("cieNmil"), and a(5) = 9 ("Nueve").
