Answer 1

Hey....

Your answer is $\bold{45}$

How?

So patter used by me to solve this problem is

a+b=a+ab

So
1+4=5
2+5=12
3+6=21
5+8=?

1+4=1+1(4)➡5
2+5=2+2(5)➡12
3+6=3+3(6)➡21
5+8=5+8(5)➡45

Answer 2

The correct answer is 45.

1 + 4 = 5

(What we did here is, we multiplied the numbers 1 × 4 =4, and then we added the first number (1) in it i.e, 1 × 4 + 1 = 5 ).

We will repeat the same method in each step. So,

2 × 5 + 2 = 12

3 × 6 + 3 = 21

5 × 8 + 5 = 45.

Therefore, the correct answer is 45.
