Sadistic
Many years ago, i passed a QI (or IQ in english?) test. Now, because i'm cruel and sadistic, I write a group of numbers:
"Find the link between the differents line of numbers" (difficulty:easy)
1
11
21
1211
111221
312211
13112221
1113213111
311312111331
I hope that i don't mistake. Good luck!
