A neat trick (Posted on 2013-12-26) Difficulty: 3 of 5
A magician asks you to choose two integers between 1 and 50 and add them.
Then add the largest two of the three integers at hand.
Then add the largest two again.
Repeat this around ten times.
Disclose to the magician your final number n.

The magician then tells you the next number.
