Why do you need to know math for this problem? If anything you need to not think about math to solve it since it requires counting letters in words.

yeah, that's what I meant

tough problem for math experts
easy problem for others

Yeah ... like I said ... nice Googling

%N A084390 a(n), when spelled in English, is the smallest positive integer > a(n-1) with exactly n letters.
%C A084390 This uses the conventions that "and" is never used, and two-digit numbers are not used before "hundred". The sequence is labeled "finite" because there is no widely accepted naming convention for arbitrarily large numbers. - David Wasserman (wasserma(AT)spawar.navy.mil), Dec 20 2004
%H A084390 Author?, <a href="http://groups.google.com.au/groups?hl=e...3a57%2540posting.google.com%26rnum%3D6">Title?</a>

%e A084390 a(5) = 7 because 'seven' has 5 letters

Please reference the definition of verbatim. And as others pointed out, math has little to do with it, as it is inexorably tied to the English language
