Halfway Between 78 and 624

When you ask "What number is halfway between 78 and 624?" 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=624.

Halfway Between Line

To find the number halfway between 78 and 624, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 78 and 624 into our formula, we get:

(78 + 624)/2 = 351

Thus, the number halfway between 78 and 624 is 351.

To check that our answer is correct, we subtract 78 from 351 and subtract 351 from 624 and compare the two numbers:

351 - 78 = 273
624 - 351 = 273

As you can see, the halfway number is 273 higher than 78 and 273 lower than 624. Therefore, our halfway between answer of 351 above is correct.
