Answer 1

We consider given table ,

1. if we consider row of table then we find that ,

Difference between $1^{st}$ and $2^{nd}$ number is $=6$

And difference between $2^{nd}$ and $3^{rd}$ number also =6

From this calculation required number is $=18$

2. if we consider column then we notice that number are start to $13$ and going up to 17

That means 13,14,15,16,17….

Difference is $=1$

Hence required number is $18$
