Question 8 Recall the sequence of Powers of 2 from Chapter 1, Table 1. Why is the Collatz conjecture correct for all the starting numbers in this sequence?Powers of 2 sequence is 2, 4, 8, 16, 32, 64,… Let’s check out Conjecture for starting numbers from this sequence The Rules of the Conjecture The process, as laid out in the text, is as follows: Start with any whole number. If the number is even, you divide it by 2. If the number is odd, you multiply it by 3 and add 1. You then take the result and repeat the process. If we start with 32 32 → 16 → 8 → 4 → 2 → 1 Similarly, If we start with 512 512 → 256 → 128 → 64 → 2 32 → 16 → 8 → 4 → 2 → 1
