Spoilers, Spoilers Everywhere!
by ePeterso2
I’ve added a new plugin to this site to make it possible to post spoilers, like this:
What is the next number in this series?
1, 11, 21, 1211, 111221, 312211, … ?

Start with 1. The string “1″ has one “1″ in it, so the next number is “11″ (one one). Now repeat the process with the new string: “11″ has two ones in it, so the next number is “21″ (two ones). The new string has one two and one one, so the next number is “1211″. And so forth.
Here’s a short description of how to use the spoiler tags.
