Halfway Between 87 and 520

When you ask "What number is halfway between 87 and 520?" 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=520.

Halfway Between Line

To find the number halfway between 87 and 520, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 87 and 520 into our formula, we get:

(87 + 520)/2 = 303.5

Thus, the number halfway between 87 and 520 is 303.5.

To check that our answer is correct, we subtract 87 from 303.5 and subtract 303.5 from 520 and compare the two numbers:

303.5 - 87 = 216.5
520 - 303.5 = 216.5

As you can see, the halfway number is 216.5 higher than 87 and 216.5 lower than 520. Therefore, our halfway between answer of 303.5 above is correct.
