0 Guest Posted April 17, 2009 Report Share Posted April 17, 2009 I think they're all prime numbers, but it might be something else since its in the word riddles forum. That's what I thought at first too but then why would 1977 be skipped? And if 2003 is next, 2 is not prime Quote Link to comment Share on other sites More sharing options...
0 Guest Posted April 17, 2009 Report Share Posted April 17, 2009 Maybe this should be in the math and logic section? I'm just a newbie, but that would make more sence to me. Quote Link to comment Share on other sites More sharing options...

0 Guest Posted April 18, 2009 Report Share Posted April 18, 2009 the last digit in the year goes in a pattern of 7, 9, 3, 7, 9, 3, etc. etc. and the years go up, so it's always the one next highest year following that pattern. i think.
