Halfway Between 78 and 778

When you ask "What number is halfway between 78 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=78 and Y=778.

Halfway Between Line

To find the number halfway between 78 and 778, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 78 and 778 into our formula, we get:

(78 + 778)/2 = 428

Thus, the number halfway between 78 and 778 is 428.

To check that our answer is correct, we subtract 78 from 428 and subtract 428 from 778 and compare the two numbers:

428 - 78 = 350
778 - 428 = 350

As you can see, the halfway number is 350 higher than 78 and 350 lower than 778. Therefore, our halfway between answer of 428 above is correct.
