numbers and watch for any unexpected jump. In this case, the jump from 45 to 47 reveals the missing number.
Now it is your turn to share the challenge. Did you find the missing number before reaching the answer, or did you have to check the fourth row twice? Send the puzzle to a friend or family member and see how quickly they spot the gap. You can even ask them to explain how they searched: did they count every number, follow the rows, or notice the jump right away?
