Most people use the OEIS to get information about a particular number sequence. If you are a new visitor, then you might ask the database if it can recognize your favorite sequence, if you have one, or you might also look at the demonstration pages to see more examples of how to use the OEIS (http://oeis.org/demo1.html).
