Updated February 12, 2018

Internet quizzes and riddles are having their moment. Viewers, including thousands of readers of AWM, eagerly await the next quiz and challenge to test their mental fortitude and quickness. Whether your favorite puzzles are the optical illusions or word games, you are in the right place. Our Quiz section includes hundreds of different mind-benders to give your brain a workout. But today, we have a very special test for you. And it involved both numbers and patterns.

Below we will share an image that includes a sequence of numbers from 1 to 49. And all you have to do is pick out which number is missing. And I promise you. A number REALLY is missing from this sequence. It is not some trick where the number is in the title or the disclaimer at the bottom. A number is missing from the series, and all you have to do is identify which number it is.

This quiz sounds easier than a lot of the other ones we’ve shared.

HINT: The number that is missing has two digits. And when you see it, you’ll be palming your forehead because you should have gotten it on your first try.

Most people take two or three tries to find the missing number. But if you take it very deliberately and slowly, you should be able to spot it on your first go around.

In an article published at the University College London’s website, we learn more about why it is so easy to miss the missing number. The researchers who wrote the article call this phenomenon “inattention blindness.” And it is much more common than you’d expect. It’s the reason we miss obvious things that are right in front of our faces.

In the publication, the researchers explain why this phenomenon is so prolific.

“Engaging attention on a high load task has a strong effect on the brain’s response to the rest of the world,” says Professor Nilli Lavie of the UCL Institute of Cognitive Neuroscience. “It reduces both the level and precision or ‘tuning’, of neural response to anything else around us that is not part of the task. These effects of load on neural response explain inattentional blindness. Although our environment hasn’t changed, the change in our brain response to load leads to an inability to perceive otherwise perfectly visible stimuli outside our focus of attention.”

Once our brains pick out a pattern, it stops searching for new and novel information. Instead, it relies on our memories of the pattern to quickly decipher the world around us.

Lavie added, “When we perform a task which demands processing a high information load, it takes up most or all of our brain capacity for perception of any other information, so our processing becomes selective. We’re able to continue attending to the relevant task, but our brain no longer responds to irrelevant information.”

Now that you know why you missed the missing number on the first try through the quiz give it another shot. Do you see the missing number in the sequence now?
