Answer must be with MATLAB, thank you!

USE MATLAB

An iterative technique is used to find an approximate solution. The true solution is $18\mathrm{.}1.$ The table below shows the approximate solution by iteration number.

$\backslash$table$[[$Iteration$,1,2,3,4],[$Approximation$,14\mathrm{.}8,16,18,17\mathrm{.}6]]$

What is the magnitude percent relative approximate error of the fourth iteration?
