Halfway Between 78 and 499

When you ask "What number is halfway between 78 and 499?" 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=499.

Halfway Between Line

To find the number halfway between 78 and 499, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 78 and 499 into our formula, we get:

(78 + 499)/2 = 288.5

Thus, the number halfway between 78 and 499 is 288.5.

To check that our answer is correct, we subtract 78 from 288.5 and subtract 288.5 from 499 and compare the two numbers:

288.5 - 78 = 210.5
499 - 288.5 = 210.5

As you can see, the halfway number is 210.5 higher than 78 and 210.5 lower than 499. Therefore, our halfway between answer of 288.5 above is correct.
