Which of the following numbers belongs to the interval (2, 5)?
Answer and explanation
Correct answer: 3
The interval (2, 5) is an open interval. It contains every real number that is greater than 2 and less than 5, but it does not contain either endpoint because both endpoints are written with round brackets. Among the given choices, 3 satisfies 2 < 3 < 5, whereas 2 and 5 are excluded and 6 lies outside the interval. Therefore, the correct answer is 3.
