Which number lies exactly midway between 1 and 4 on the number line?
Answer and explanation
Correct answer: 2.5
The number exactly midway between two numbers is their average. Thus, \(\frac{1+4}{2}=\frac{5}{2}=2.5\). Hence, 2.5 is correct because it is 1.5 units from both 1 and 4. The number 3 is closer to 4, while 2 is closer to 1. Exam tip: Find the midpoint of \(a\) and \(b\) using \(\frac{a+b}{2}\).
