Now that's a tricky math puzzle! Brain Dare posted this brain teaser on their FB page only to receive tons of comments by people who are desperately trying to solve it. The puzzle doesn’t give much away, but to obtain the solution to the fourth equation, you must uncover the method used to answer the previous three equations. It is essential that you can find the hidden algorithm.

It might seem like there are two solutions for this riddle, but there is actually only one that's correct. So, can you find the missing number?


According to Brain Dare, the solution is 96. Here’s how it goes:

Their solution involves introducing multiplication into the mix. First, you multiply the first number by the second number. Then, you simply add the product of those two numbers to the first number. Like so:

1 + (1 x 4) = 5

2 + (2 x 5) = 12

3 + (3 x 6) = 21

8 + (8 x 11) = 96

However, if you did manage to work out a solution for the sum yourself, there’s a fair chance you came to the answer 40 instead. Here's how you come to that answer:

1 + 4 = 5

2 + 5 + 5 = 12

3 + 6 + 12 = 21

8 + 11 + 21 = 40

Of course, there’s no right or wrong answer, even if there is an "officially right" solution.

  1. Even the second method shown by you is correct only the approach is wrong

    1+4 =5
    2+5+5 =12
    3+6+12 =21
    4+7+21 =32
    5+8+32 =45
    6+9+45 =60
    7+10+60 =77

    And finally
    8+11+77=96

    So the right answer is 96 eventually.
