Halfway Between 72 and 391

When you ask "What number is halfway between 72 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=72 and Y=391.

Halfway Between Line

To find the number halfway between 72 and 391, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 72 and 391 into our formula, we get:

(72 + 391)/2 = 231.5

Thus, the number halfway between 72 and 391 is 231.5.

To check that our answer is correct, we subtract 72 from 231.5 and subtract 231.5 from 391 and compare the two numbers:

231.5 - 72 = 159.5
391 - 231.5 = 159.5

As you can see, the halfway number is 159.5 higher than 72 and 159.5 lower than 391. Therefore, our halfway between answer of 231.5 above is correct.
