Answer 2

• As per the given data in the question, we have to find the fourth proportional to $4,12$ and $16.$

        Let the fourth proportional to $4,12$ and $16$ be $x.$

        Then, $4:12::16:x$

         $\Rightarrow 4\times x=12\times 16$

         $\Rightarrow x=\frac{12\times16}{4}\\\Rightarrow 12\times4=48.$

         The fourth proportion of $4,12$ and $16$ will be $48.$
