According to several sources on the internet, there are two viable solutions to this math riddle. That’s good news for you! It means your chances of having the correct answer have just doubled! Let’s see the first solution and find out if it was what you also got for your answer.

This solution was the most commonly found among those who answered correctly. The missing number is 40. To get that, we would need to realize a pattern within the math problem. If you add each total to the following equation, you will eventually end up with 40.

1 + 4 = 5
5 + 2 + 5 = 12
12 + 3 + 6 = 21
21 + 8 + 11 = 40

The second correct answer to solve this mystery is 96. However, this answer was not commonly found and is a bit trickier. To reach the answer of 96, you would need to multiply the first number in each line by the second number, then add the product to the first number.

1 + (1 x 4) = 5
2 + ( 2 x 5) = 12
3 + (3 x 6) = 21
8 + (8 x 11) = 96
