Question

The value of question mark is :

Answer 1

Working in rows, the number in the centre equals the sum of the left and right hand numbers, divided by 3.

In the first row, middle value is $=\frac{5+7}{3}=\frac{12}{3}=4$

In the second row, middle value is $=\frac{12+6}{3}=\frac{18}{3}=6$

Hence, required value = $\frac{7+2}{3}=\frac{9}{3}=3$
