Halfway Between 87 and 113

When you ask "What number is halfway between 87 and 113?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=87 and Y=113.

Halfway Between Line

To find the number halfway between 87 and 113, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 87 and 113 into our formula, we get:

(87 + 113)/2 = 100

Thus, the number halfway between 87 and 113 is 100.

To check that our answer is correct, we subtract 87 from 100 and subtract 100 from 113 and compare the two numbers:

100 - 87 = 13
113 - 100 = 13

As you can see, the halfway number is 13 higher than 87 and 13 lower than 113. Therefore, our halfway between answer of 100 above is correct.
