Final answer:
A number between 2.981 and 2.982 is 2.9815.
Step-by-step explanation:
To determine a number between 2.981 and 2.982, you can consider the midpoint between these two values. The midpoint is calculated by adding the two values and dividing the sum by 2. Therefore, (2.981 + 2.982) ÷ 2 = 5.963 ÷ 2 = 2.9815.
Another approach is to recognize that the difference between the two given numbers is 0.001. Therefore, to find a number exactly in the middle of them, add half of this difference to the smaller number. In this case, 2.981 + (0.001 ÷ 2) = 2.981 + 0.0005 = 2.9815. This calculation ensures the selected number lies equidistant from both 2.981 and 2.982, thereby representing a value between the two.
Therefore, the number 2.9815 lies between 2.981 and 2.982, serving as an accurate midpoint value between the two given numbers.
