How to Calculate the Number in the Middle of 15 and 24
To calculate the number in the middle of two values, we are essentially seeking the mean or average of those two numbers. This can be done by adding the two numbers together and then dividing by the number of values, which is 2 in this case. Thus, the calculation would be (15 + 24)/2.
Let's do the math: (15 + 24)/2 = 39/2 = 19.5.
Therefore, the number in the middle of 15 and 24 is 19.5.
