Question

Plz answer this it's urgent with explanation

Answer 1

Answer :

The pattern I'm noticing in this question is that the first number of the addition is multiplied to the next's successor.

This way -

1+4 → 1×(4+1) = 5

2+5 → 2×(5+1) = 13

3+6 → 3×(6+1) = 21

So,

5+8 would be → 5×(8+1) = 5×9 = 45

Thus, the answer is 45
