Answer 1

Solution:

It is very tricky Question but we can solve this easily. Let us understand this question, Yeah! I got it how to solve this problem;

Let to be + = ×

Note: We will add every first Number of each queries.

Now, Arrange it I'm particular form!

Query 1. 1 + 4 = 5

☞ 1 × 4 = 5

☞ 1 × 4 + 1 = 5 { Solved}

Query 2. 2 + 5 = 12

☞ 2 + 5 = 12

☞ 2 × 5 + 2 = 12

Now, According to the Question Statement!

☞5+8= ?

☞ 5 × 8 + 5 = 45

Therefore, Next term will be 45.

Answer 2

Answer: The answer is 45.

Step-by-step explanation:

In the above pattern,

1 + 4 = 5

2+5=12

3+6=21

5+8= ?

The trick in the question is (a × b) + a = sum.

In the above pattern :

let the every first number be "a"

every second be "b"

Here,

(1 × 4 ) + 1 = 5

( 2 × 5) + 2 = 12

(3 × 6 ) + 3 = 21

Similarly,

( 5 × 8 ) + 5 = 45
