Halfway Between 80 and 678

When you ask "What number is halfway between 80 and 678?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=80 and Y=678.

Halfway Between Line

To find the number halfway between 80 and 678, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 80 and 678 into our formula, we get:

(80 + 678)/2 = 379

Thus, the number halfway between 80 and 678 is 379.

To check that our answer is correct, we subtract 80 from 379 and subtract 379 from 678 and compare the two numbers:

379 - 80 = 299
678 - 379 = 299

As you can see, the halfway number is 299 higher than 80 and 299 lower than 678. Therefore, our halfway between answer of 379 above is correct.
