This riddle looks like a simple number question, but the wording hides a clever trick.
Most people immediately think of the number 5 because it sits between 4 and 6. However, the riddle clearly says that 5 is not the answer.
Instead of thinking mathematically, read the sentence literally. In the phrase “4 and 6,” one word is positioned directly between the two numbers.
Answer: The word “and.”
