What is the value indicated by the number line with a mark at 2.5?

• A. 1.5
• B. 2
• C. 2.5
• D. 3

Answer: (B)

The value indicated by the number line at the mark of 2.5 is indeed 2.5. A number line represents real numbers in a straight line, where each point corresponds to a specific value. The mark at 2.5 directly shows that it is the halfway point between the whole numbers 2 and 3. Since the question asks specifically for the value indicated by the mark, the correct answer is simply the number itself that appears at that exact position on the number line, which is 2.5. In this case, the other answers do not represent the mark at 2.5. The value of 1.5 is to the left of 2, and does not correlate with the indicated mark. The value of 2 is indeed a whole number but it does not match the 2.5 mark; it’s located to the left of 2.5. Finally, the value of 3 is located to the right of 2.5 on the number line, making it also incorrect as an indication of the mark placed at 2.5. Thus, the correct interpretation of the number line's marking leads to identifying the value as 2.5.
