    Correct Answer
    A. 26
    Explanation
    The given numbers are 24, 26, and 28. To find the arithmetic mean (average), we add up all the numbers and divide the sum by the total count of numbers. Adding 24, 26, and 28 gives us 78. Since there are three numbers, we divide 78 by 3 to get the arithmetic mean. Therefore, the arithmetic mean of 24, 26, and 28 is 26.
