Halfway Between 78 and 507

When you ask "What number is halfway between 78 and 507?" 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=507.

Halfway Between Line

To find the number halfway between 78 and 507, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 78 and 507 into our formula, we get:

(78 + 507)/2 = 292.5

Thus, the number halfway between 78 and 507 is 292.5.

To check that our answer is correct, we subtract 78 from 292.5 and subtract 292.5 from 507 and compare the two numbers:

292.5 - 78 = 214.5
507 - 292.5 = 214.5

As you can see, the halfway number is 214.5 higher than 78 and 214.5 lower than 507. Therefore, our halfway between answer of 292.5 above is correct.
