Halfway Between 72 and 780

When you ask "What number is halfway between 72 and 780?" 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=780.

Halfway Between Line

To find the number halfway between 72 and 780, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 72 and 780 into our formula, we get:

(72 + 780)/2 = 426

Thus, the number halfway between 72 and 780 is 426.

To check that our answer is correct, we subtract 72 from 426 and subtract 426 from 780 and compare the two numbers:

426 - 72 = 354
780 - 426 = 354

As you can see, the halfway number is 354 higher than 72 and 354 lower than 780. Therefore, our halfway between answer of 426 above is correct.
