Answer 2

The missing number is 58.

Step-by-step explanation:

We have,

1 + 2 = 21

2 + 3 = 36

3 + 4 = 43

To find, the value of 4 + 5 = ?

The pattern follow:

Reverse numbers, Reverse numbers + 4, Reverse numbers, Reverse numbers + 4, .....

1 + 2 ⇒ Reverse number 2,1 = 21

2 + 3 ⇒ Reverse number + 4 =  32 + 4 = 36

3 + 4 ⇒ Reverse number 4, 3 = 43

Similarly,

? = 4 + 5 ⇒ Reverse number + 4 =  54 + 4 = 58

Thus, the missing number is 58.
