Using the recursion equation, it is found that the value of the 2nd iterate is:
[tex]x_2 = 3.16228[/tex]
The value of the nth iteration is given by:
[tex]x_n = \frac{x_{n-1} + \frac{10}{x_{n-1}}}{2}[/tex]
The initial estimate is:
[tex]x_0 = 3.1[/tex]
Hence, the 1st iterate is given by:
[tex]x_1 = \frac{x_0 + \frac{10}{x_0}}{2} = \frac{3.1 + \frac{10}{3.1}}{2} = 3.1629[/tex]
The 2nd iterate is:
[tex]x_2 = \frac{x_1 + \frac{10}{x_1}}{2} = \frac{3.1629 + \frac{10}{3.1629}}{2} = 3.16228[/tex]
Thus, the fourth option is correct.
