Halfway Between 39 and 87

When you ask "What number is halfway between 39 and 87?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=39 and Y=87.

Halfway Between Line

To find the number halfway between 39 and 87, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 39 and 87 into our formula, we get:

(39 + 87)/2 = 63

Thus, the number halfway between 39 and 87 is 63.

To check that our answer is correct, we subtract 39 from 63 and subtract 63 from 87 and compare the two numbers:

63 - 39 = 24
87 - 63 = 24

As you can see, the halfway number is 24 higher than 39 and 24 lower than 87. Therefore, our halfway between answer of 63 above is correct.
