WebAs an example, let’s go back to the “3N+1” problem that was discussed in Subsection 3.2. (Recall that a 3N+1 sequence is computed according to the rule, “if N is odd, multiply by 3 and add 1; if N is even, divide by 2; continue until N is equal to 1.” For example, starting from N=3 we get the sequence: 3, 10, 5, 16, 8, 4, 2, 1.) WebWhen n is an odd number the out put is either even or odd. When n is odd, we use the out put as the next input. And if n = even we know it will have an output of (whole number.5) So we want the initial input to be odd, and then it lead to consecutive inputs being odd. For example the initial input of 15 has an output 23. WebIf 1-n 2 > 0 then 3n-2 is an even integer. Proof: let 1-n 2 > 0. Then n = 0. Thus 3n-2 = 3(0) - 2 = 2 is an even integer.⃗ .
