Halfway Between 72 and 840

When you ask "What number is halfway between 72 and 840?" 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=840.

Halfway Between Line

To find the number halfway between 72 and 840, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 72 and 840 into our formula, we get:

(72 + 840)/2 = 456

Thus, the number halfway between 72 and 840 is 456.

To check that our answer is correct, we subtract 72 from 456 and subtract 456 from 840 and compare the two numbers:

456 - 72 = 384
840 - 456 = 384

As you can see, the halfway number is 384 higher than 72 and 384 lower than 840. Therefore, our halfway between answer of 456 above is correct.
