Halfway Between 78 and 422

When you ask "What number is halfway between 78 and 422?" 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=422.

Halfway Between Line

To find the number halfway between 78 and 422, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 78 and 422 into our formula, we get:

(78 + 422)/2 = 250

Thus, the number halfway between 78 and 422 is 250.

To check that our answer is correct, we subtract 78 from 250 and subtract 250 from 422 and compare the two numbers:

250 - 78 = 172
422 - 250 = 172

As you can see, the halfway number is 172 higher than 78 and 172 lower than 422. Therefore, our halfway between answer of 250 above is correct.
