A simple sequence of numbers that is a lot more complicated than you may think.
Inspiration from VSauce: https://www.youtube.com/watch?v=ti8ZdImveB0 Music is Strad by C418. TRANSCRIPT This is Recaman's sequence. It works on simple rules. You start at 0, then go forward 1, then 2, then 3, and so on. However. If going backwards that same amount lands you on a positive number that is not already on the sequence, it goes backwards. The first number to appear twice is 42.
