Halfway Between 54 and 100

When you ask "What number is halfway between 54 and 100?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=54 and Y=100.

Halfway Between Line

To find the number halfway between 54 and 100, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 54 and 100 into our formula, we get:

(54 + 100)/2 = 77

Thus, the number halfway between 54 and 100 is 77.

To check that our answer is correct, we subtract 54 from 77 and subtract 77 from 100 and compare the two numbers:

77 - 54 = 23
100 - 77 = 23

As you can see, the halfway number is 23 higher than 54 and 23 lower than 100. Therefore, our halfway between answer of 77 above is correct.
