Halfway Between 5 and 100

When you ask "What number is halfway between 5 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=5 and Y=100.

Halfway Between Line

To find the number halfway between 5 and 100, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 5 and 100 into our formula, we get:

(5 + 100)/2 = 52.5

Thus, the number halfway between 5 and 100 is 52.5.

To check that our answer is correct, we subtract 5 from 52.5 and subtract 52.5 from 100 and compare the two numbers:

52.5 - 5 = 47.5
100 - 52.5 = 47.5

As you can see, the halfway number is 47.5 higher than 5 and 47.5 lower than 100. Therefore, our halfway between answer of 52.5 above is correct.
