Halfway Between 78 and 478

When you ask "What number is halfway between 78 and 478?" 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=478.

Halfway Between Line

To find the number halfway between 78 and 478, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 78 and 478 into our formula, we get:

(78 + 478)/2 = 278

Thus, the number halfway between 78 and 478 is 278.

To check that our answer is correct, we subtract 78 from 278 and subtract 278 from 478 and compare the two numbers:

278 - 78 = 200
478 - 278 = 200

As you can see, the halfway number is 200 higher than 78 and 200 lower than 478. Therefore, our halfway between answer of 278 above is correct.
