$\left [ \left \{ \left ( 20-18-\square \right ) +2\right \} X4\right ]\div 14=2$

$\left [ \left \{ \left ( 20-18-\square \right ) +2\right \} X4\right ]=28, since, \frac{28}{14}=2$

$\left \{ \left ( 20-18-\square \right )+2 \right \}=7, since 7X4=28$

$\left ( 20-18-\square \right )=5, since 5+2=7$

$18-\square =15, since 20-15=5$

$\square =3, since 18-15=3$

3 should be there in the box.
