• To find:- 6+25=?

• Solution:- According to the question ,the format is like ,

A+B=(A+B)+3 [if one is even number in between A & B ]

A+B=(A+B)+4 [ if there are no even number in between A & B]

according to the format

2+7=9+3= 12 (as 7 is even number in between 2 &7)

3+12=15+3=18. (as 3 is even number in between 3 &12)

4+20=24+4 (as there are no even number in between 4&20)

So, 6+25=31+3= 34 ( as 25 is a even number in between 6&25)
