Halfway Between 30 and 778

When you ask "What number is halfway between 30 and 778?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=30 and Y=778.

Halfway Between Line

To find the number halfway between 30 and 778, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 30 and 778 into our formula, we get:

(30 + 778)/2 = 404

Thus, the number halfway between 30 and 778 is 404.

To check that our answer is correct, we subtract 30 from 404 and subtract 404 from 778 and compare the two numbers:

404 - 30 = 374
778 - 404 = 374

As you can see, the halfway number is 374 higher than 30 and 374 lower than 778. Therefore, our halfway between answer of 404 above is correct.
