Answer 1

Answer:

In right column it is in sequence.

3+(4)=7

7+(6)=13

13+(8)=21

21+(10)=31

Answer 2

$\Large{\underline{\underline{\bf{Solution :}}}}$

☯ To Find :

We have to find the value of x from the given attachment.

$\rule{200}{1}$

☯ Solution :

If we see Left side properly we can see that the Left side numbers are in A.P and commpn difference is also same.

But, Right side is in sequence as difference is not same.

Firstly, we will find difference betwwen 3 and 7.

→ 7 - 3

→ 4

$\rule{150}{2}$

Now, we will find difference of 7 and 13.

→ 13 - 7

→ 6

$\rule{150}{2}$

Similarly, Now difference must be 8 because there is gap of 2 in each case.

→ 8 = x - 13

→ x = 13 + 8

→ x = 21

$\large{\implies{\boxed{\boxed{\sf{x = 21}}}}}$

$\rule{150}{2}$

Now, there must be difference of 10 as there is gap of 2. If our difference would be 10. So, our answer will be verified.

→ 31 - 21

→ 10

Hence Verified
