Collatz conjecture: start with any positive integer n.Next termis obtained from the previous term as follows:
if the previous term is even, the next term is one half the previous term.
Collatz conjecture: start with any positive integer n.Next term is obtained from the previous term as follows:
if the previous term is even, the next term is one half of the previous term.
If the previous term is odd, the next term is 3 times the previous term plus 1.
The conjecture states the sequence will always reach 1 regaardess of starting n.
The conjecture states the sequence will always reach 1 regaardless of starting value n.
