Tricky brainteaser can only be solved within 10 seconds by people with an IQ of 135 or higher

A new math brainteaser claims that only people with high IQs can solve this in nine seconds or less.

The puzzle challenges viewers to notice the pattern of five numbers placed in pie wedges to identify the missing piece.

The image shows six triangular wedges in a circle with the numbers 4, 7, 13, 25 and 49 placed clockwise, with a question mark in the last part.

If you manage to compose the name of the country within the allotted time frame, it indicates that your intelligence score is 135 or higher.

To solve this brainteaser, viewers must study the numbers and identify a pattern between the numbers.

Here’s a hint: you need to look at the mathematical difference between the two.

Starting with the number at the top right and moving clockwise, viewers should look at the difference between four and seven, which is three.

The next step is to find the difference between seven and 13, which is six: double the difference between the previous two numbers.

Then you have to compare 13 and 25 to get 12, followed by 25 and 49, which is 24.

You may notice that with each series the number difference doubles, so if you continue this pattern you have to double 24 to get 48.

Then add 48 to the last number before the question mark and that gives you the answer: 97.

Another pattern would be to multiply the number in each wedge by two and subtract one to get the next sequence.

Starting with the four in the top right corner, the difference between each number doubles, meaning the answer is 97

If you didn’t get the answer within the nine-second time frame, don’t be discouraged by having an IQ of less than 135.

The average IQ – which stands for intelligence quotient – ​​in the US is around 98, with men averaging 99 and women averaging 97.

Gifted people often achieve an average IQ score of 120 to 140, but only about two percent of the U.S. population scores above 130, which gives them genius status.

Brainteasers are useful for improving one’s logic and problem-solving skills, as well as improving one’s concentration, spatial reasoning, and even IQ.

A University of Michigan study found that people who worked on challenging brainteasers for at least 25 minutes every day increased their IQ by as much as four points.

These games also work on both hemispheres: the left hemisphere controls your logical and analytical thinking and the right hemisphere is responsible for creativity.

The brain is like a muscle and those who train it regularly with brain teasers will become more intelligent in the long run.
