45 is the answer if the given pattern is 1+4=5 2+5=12 3+6=21 5+8= ?

Given:

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

To find:

5+8= ?

Solution

The pattern of the above question is the first number is multiplied by the addition of first and the another number that is in addition with the first number, as we can see below

1 + 4 = 5 can be written as $1 \times(1+4)=5$

The digit one is multiplied by the sum of one and four, the same for the other numbers been solved below

2 + 5 = 12 can be written as $2 \times(1+5)=12$

3 + 6 = 21 can be written as $3 \times(1+6)=21$

Using the same pattern we find the value of 5 + 8,

5 + 8 = 45 can be written as $5 \times(1+8)=45$

Therefore, the value of 5 + 8 = 45
