Answer 2

All the series follow a certain pattern. In order to solve the missing value, one need to understand the pattern.

Given: A table with numbers

In the first row, the numbers are $3,6,9$

The pattern followed here is, multiplying the first two numbers and divinding the product by two

$\implies \frac{3\times6}{2}$

$\implies \frac{18}{2}$

$\implies 9$

Check the second row. The numbers are $5,8,20$. According to the pattern,

$\implies \frac{ 5\times 8}{2}$

$\implies \frac{ 40}{2}$

$\implies 20$

So the missing number will be

$\implies \frac{4\times7}{2}$

$\implies \frac{28}{2}$

$\implies 14$
