Halfway Between 78 and 487

When you ask "What number is halfway between 78 and 487?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=78 and Y=487.

Halfway Between Line

To find the number halfway between 78 and 487, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 78 and 487 into our formula, we get:

(78 + 487)/2 = 282.5

Thus, the number halfway between 78 and 487 is 282.5.

To check that our answer is correct, we subtract 78 from 282.5 and subtract 282.5 from 487 and compare the two numbers:

282.5 - 78 = 204.5
487 - 282.5 = 204.5

As you can see, the halfway number is 204.5 higher than 78 and 204.5 lower than 487. Therefore, our halfway between answer of 282.5 above is correct.
