Halfway Between 78 and 424

When you ask "What number is halfway between 78 and 424?" 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=424.

Halfway Between Line

To find the number halfway between 78 and 424, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 78 and 424 into our formula, we get:

(78 + 424)/2 = 251

Thus, the number halfway between 78 and 424 is 251.

To check that our answer is correct, we subtract 78 from 251 and subtract 251 from 424 and compare the two numbers:

251 - 78 = 173
424 - 251 = 173

As you can see, the halfway number is 173 higher than 78 and 173 lower than 424. Therefore, our halfway between answer of 251 above is correct.
