Press space bar and enter a number to test for the Collatz Conjecture or Hailstone Numbers The collatz conjecture states that if you start with any number, then if it's even, you divide it by 2. If it's odd, you multiply the number by 3 and add 1. Example: 7. 7 is odd, so 7*3+1=22, 22/2=11, 11*3+1=34, then you go to 17, 52, 26, 13, 40, 20,10, 5, 16, 8, 4, 2, 1, 4, 2, 1, wait a minute. You get stuck at 4, 2, 1,. The actual question is whether every number gets stuck at 4, 2, 1. This tests 1 at a time, but I am making/have made one that can test for all numbers.
look inside to change the speed of each term. also if you go to calculator soup large powers and copy paste a really big power of 2, its always even so it only goes down lastly i made this is under 10 mins any% This hasn't been proven, but so far up to numbers that have TONS of digits. Way past googol.
