Thanks to everyone who wrote to me about this problem.

And especially to Paul Leopardi, who found the solution.

I'm not sure this sequence should remain in the OEIS,
but one of the goals of the database, right from the
beginning, 40 years ago, has always been to include
sequences found on quizzes.  So I am going to leave it
in for the moment.  Here's the revised entry:

%I A101385
%S A101385 2616,3,11,10850,0,25,2038
%N A101385 A puzzle: replace the 0 term by the correct answer.
%C A101385 Apparently there have been over 100 puzzles on the Neopets web site, and the answe\
rs to puzzles 9, 16, 25, etc. are as follows:
%C A101385 9: 2616
%C A101385 16: 3
%C A101385 25: 11
%C A101385 36: 10850
%C A101385 49: Abracadabra
%C A101385 64: 25
%C A101385 100: 2038
%C A101385 So the missing term is probably Abracadabra.
%H A101385 Neopets, <a href="http://neopets.com/">Neopets Web Site</a>
%H A101385 Neopets, <a href="http://neopets.com/newnt/index.phtml?section=4080&week=26">Conun\
drum for Week 26</a>
%K A101385 nonn
%O A101385 1,1
%A A101385 njas, Jan 14 2005
%E A101385 Thanks to Matt Sauers and Alyxandra Ramsey, who told me about the sequence, to Pau\
l C. Leopardi, who found the solution, and to many other people who sent comments.


What do seqfans think?  Should I leave it in?

Because of the 0 term, it is not identical to the Neopets puzzle.
