Here’s a fun brain teaser designed to put your observation skills to the test! The grid features numbers ranging from 1 to 15, but one of them is missing. At first glance, the numbers appear to be scattered randomly, making the missing piece surprisingly easy to overlook. Your task is to identify the number that doesn’t belong before checking the solution!

Take a careful look at the sequence: 15, 4, 9, 1, 7, 14, 3, 10, 5, 8, ?, 6, 2, 11 and 13. There’s no need for complicated calculations or mathematical formulas to crack this puzzle. Simply focus on the numbers already shown and count from 1 to 15, mentally crossing off each one as you find it. Can you discover the missing number before time runs out? ⏱️

The correct answer is 12! 🎯 All the numbers from 1 to 11 are present, along with 13, 14 and 15. That means 12 is the only number missing from the sequence. Although the solution seems obvious once revealed, the scattered arrangement can easily distract your attention and cause you to overlook the simplest detail.

Did you manage to find 12 straight away, or did you need to examine the sequence more than once? Sometimes the easiest challenges can be surprisingly tricky! Share how many seconds it took you to solve it and see whether your friends can beat your time. 😄
