Halfway Between 10 and 87

When you ask "What number is halfway between 10 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=10 and Y=87.

Halfway Between Line

To find the number halfway between 10 and 87, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 10 and 87 into our formula, we get:

(10 + 87)/2 = 48.5

Thus, the number halfway between 10 and 87 is 48.5.

To check that our answer is correct, we subtract 10 from 48.5 and subtract 48.5 from 87 and compare the two numbers:

48.5 - 10 = 38.5
87 - 48.5 = 38.5

As you can see, the halfway number is 38.5 higher than 10 and 38.5 lower than 87. Therefore, our halfway between answer of 48.5 above is correct.
