Halfway Between 78 and 323

When you ask "What number is halfway between 78 and 323?" 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=323.

Halfway Between Line

To find the number halfway between 78 and 323, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 78 and 323 into our formula, we get:

(78 + 323)/2 = 200.5

Thus, the number halfway between 78 and 323 is 200.5.

To check that our answer is correct, we subtract 78 from 200.5 and subtract 200.5 from 323 and compare the two numbers:

200.5 - 78 = 122.5
323 - 200.5 = 122.5

As you can see, the halfway number is 122.5 higher than 78 and 122.5 lower than 323. Therefore, our halfway between answer of 200.5 above is correct.
