b = 5
Answer:
I think the answer is C but I'm not too sure so if it doesn't sound right don't click it cuz I don't want you get the answer wrong
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.
