    Interesting way to answer it, however it's a sad numbers cycle that repeats itself :

    Let's take 3 by example ->
    3² = 9, 9² = 81, 8² + 1² = 65, 6² + 5² = 61, 6²+1²= 37 (the cycle starts) , 3² + 7² = 58, 5²+8²= 89… and so it goes.

    @Stephan:

    > 4² + 4 + 5 = 4.4 + 4 + 5 = 5.4 + 5 = 5.5 = 5².
    > 13² + 13 + 14 = 13.13 + 13 + 14 = 14.13 + 14 = 14.14 = 14².
    > n² + n + (n + 1) = (n + 1).n + (n + 1) = (n + 1)(n + 1) = (n + 1)2

    I think you just conquered the game. xD
  2. Hey, this game requires some nice knowledge of mathematics.
    It's pretty simple, someone starts by posting an equation, a sequence, or even a number.
    The next one should guess it, then he posts an another one, and going on.

    I'll start :p

    1,2,3,5,8,13,21,34,55,89,144,233,377,610,987,1597…

    > And do any of those earthquakes cause a tsumami to cover the Pacific Ocean, threatening many of the islands on it? You cannot exactly say that it doesn't matter after it has killed so many people.

    True,  not all of them caused such a distaster, i also heard authorities are shutting down nuclear stations, so they can avoid explosions.
