Halfway Between 80 and 391

When you ask "What number is halfway between 80 and 391?" 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=391.

Halfway Between Line

To find the number halfway between 80 and 391, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 80 and 391 into our formula, we get:

(80 + 391)/2 = 235.5

Thus, the number halfway between 80 and 391 is 235.5.

To check that our answer is correct, we subtract 80 from 235.5 and subtract 235.5 from 391 and compare the two numbers:

235.5 - 80 = 155.5
391 - 235.5 = 155.5

As you can see, the halfway number is 155.5 higher than 80 and 155.5 lower than 391. Therefore, our halfway between answer of 235.5 above is correct.
