Only 2 percent of people can solve this math problem – but it's actually very easy

A YouTube account that regularly shares various riddles and problems to entertain its audience has stunned viewers after posting a math problem that seems almost impossible to figure out at first.

To add to the difficulty of solving it, the Nature of Puzzle account said that only 2% of people solve the problem without the help of others.

The video includes the problem to encourage viewers to solve it themselves.

Then, at the end of the clip, you can also find the solution to see if you are right, Telegrafi reports.

10 + 17 = 54

15 + 19 = 136

17 + 18 = 210

19 + 21 = ?

Finding the correct number to answer the final question, 19 + 21, can seem like an extremely difficult task.

However, if you look closely at the numbers and start thinking, you can find the right solution.

To find the correct answer to this math problem, you'll need to look at each number individually and see that they all follow the same logic.

Basically, you will need to add the two numbers, then multiply the total following a x2, x4, x6 or x8 pattern and you will find the solution.

To break down the task, it works like this:

10 + 17 = 27, then multiply x2, 27 x 2 = 54

15 + 19 = 34, then multiply x4, 34 x 4 = = 136

17 + 18 = 35, then multiply x6, 35 x 6 = 210

This means that to find the answer to the final question, you will have to do exactly the same thing and multiply the result x6.

The answer is: 19 + 21 = 40, then multiply x8, 40 x 6 = 320

So the correct answer to this problem is 320. Did you find the answer before reading the explanation? /Telegraph/
