Halfway Between 78 and 634

When you ask "What number is halfway between 78 and 634?" 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=634.

Halfway Between Line

To find the number halfway between 78 and 634, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 78 and 634 into our formula, we get:

(78 + 634)/2 = 356

Thus, the number halfway between 78 and 634 is 356.

To check that our answer is correct, we subtract 78 from 356 and subtract 356 from 634 and compare the two numbers:

356 - 78 = 278
634 - 356 = 278

As you can see, the halfway number is 278 higher than 78 and 278 lower than 634. Therefore, our halfway between answer of 356 above is correct.
