Halfway Between 78 and 623

When you ask "What number is halfway between 78 and 623?" 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=623.

Halfway Between Line

To find the number halfway between 78 and 623, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 78 and 623 into our formula, we get:

(78 + 623)/2 = 350.5

Thus, the number halfway between 78 and 623 is 350.5.

To check that our answer is correct, we subtract 78 from 350.5 and subtract 350.5 from 623 and compare the two numbers:

350.5 - 78 = 272.5
623 - 350.5 = 272.5

As you can see, the halfway number is 272.5 higher than 78 and 272.5 lower than 623. Therefore, our halfway between answer of 350.5 above is correct.
