Answer 2

Given :

1 + 4 = 5

2 + 5 = 12

3 + 6 = 21

To find :

Using the same pattern , we have to find the value of 5 + 8 .

Solution :

On observing we can conclude that , the result of multiplying of the given two number is added to the first number , is the answer to that calculation .

( 1 * 4 ) + 1 = 5

( 2 * 5) + 2 = 12

( 3 * 6 ) + 3 =21

similarly ,

 5 +8 → ( 5 * 8 ) + 5

         → 40 + 5

         → 45

5 + 8 = 45
