Answer 1

Solution :

In this Question , We have Provided with a puzzle of verbal Category and we need to find the proper method which will fit to get the missing Sequence of verbal .

1 + 4 = 5

Let it as a + b = c

a * (b + 1) = c

Similarly ,

⇒ 1 * (4+1) = 5

⇒ 1* 5 = 5

2 + 5 = 12

Let it as a + b = c

a * (b+ 1) = c

Similarly ,

⇒ 2 * (5+1) = 12

⇒ 2* 6 = 12

3 + 6 = 21

Let it as a + b = c

a * (b+1) = c

Similarly ,

⇒ 3 * (6+1) = 21

⇒ 3 * 7 = 21

5 + 8 = ?

Let it as a + b = c

a * (b+1) = c

Similarly ,

⇒ 5 * (8 + 1) = ?

⇒ 5 * 9 = 45

Therefore , Our Required answer is 45
