Halfway Between 100 and 772

When you ask "What number is halfway between 100 and 772?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=100 and Y=772.

Halfway Between Line

To find the number halfway between 100 and 772, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 772 into our formula, we get:

(100 + 772)/2 = 436

Thus, the number halfway between 100 and 772 is 436.

To check that our answer is correct, we subtract 100 from 436 and subtract 436 from 772 and compare the two numbers:

436 - 100 = 336
772 - 436 = 336

As you can see, the halfway number is 336 higher than 100 and 336 lower than 772. Therefore, our halfway between answer of 436 above is correct.
