Halfway Between 78 and 563

When you ask "What number is halfway between 78 and 563?" 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=563.

Halfway Between Line

To find the number halfway between 78 and 563, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 78 and 563 into our formula, we get:

(78 + 563)/2 = 320.5

Thus, the number halfway between 78 and 563 is 320.5.

To check that our answer is correct, we subtract 78 from 320.5 and subtract 320.5 from 563 and compare the two numbers:

320.5 - 78 = 242.5
563 - 320.5 = 242.5

As you can see, the halfway number is 242.5 higher than 78 and 242.5 lower than 563. Therefore, our halfway between answer of 320.5 above is correct.
