    Why do you want to know ? Is it because you have a lot of time on you hands and needed to ask a question about number sequencing ?

    A pretty big number:

    13112221

    A classic sequence, though one that has nothing to do with mathematics. Here's a hint - each entry in the sequence is a description of what came before.

    See here. You could try this site anytime you have a sequence. It doesn't have all them, though.
