D) is the answer i already done that question
Using the recursion equation, it is found that the value of the 2nd iterate is:

<h3>What is the recursive equation?</h3>
The value of the nth iteration is given by:

The initial estimate is:

Hence, the 1st iterate is given by:

The 2nd iterate is:

Thus, the fourth option is correct.

Let’s take the number .666666 repeating
If we turn it into a fraction it’s 2/3.
It doesn’t matter how many numbers repeat to write a fraction.
Hope this helps.
