Today at school, someone has drawn on the board a cartoon of the math teacher, and against all odds, I have not done anything funny. As the culprit has not confessed, he has punished us all without leaving until we solve the following problem:

In the following sequence of numbers: 12345678910111213….

**In which position will 5002 appear for the first time?**

#### Solution

**The position in which it appears is between 2500 and 2501**… 24992**5002**501…

And the digits, if I'm not mistaken, are 8,891. I'm going home!
