xdbtcp Apr 24, 2009	Interesting - I got it right, but I just noticed that the first digit of each number was the last digit of the previous number....
Paladin Apr 24, 2009	I solved this by knowing that the numbers next to each other were the same. Fun teaser nonetheless.
Hadleigh Apr 26, 2009	It was a fun teaser albeit pretty easy. No need for a hint.
Nerine May 01, 2009	Confusing at first but the hint gave it away. Even if it was easy I still wouldn't have got it though; I'm hopeless at sequences!
bradon182001 May 02, 2009	Good teaser. Well thought out and fun to work. Thanks for posting.
racoonieboy Aug 05, 2010	A more suitable answer would be: The first digit of any number is the same as the second digit before it. I don't think the eleven thingy makes any sense.
