Halfway Between 100 and 656

When you ask "What number is halfway between 100 and 656?" 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=656.

Halfway Between Line

To find the number halfway between 100 and 656, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 656 into our formula, we get:

(100 + 656)/2 = 378

Thus, the number halfway between 100 and 656 is 378.

To check that our answer is correct, we subtract 100 from 378 and subtract 378 from 656 and compare the two numbers:

378 - 100 = 278
656 - 378 = 278

As you can see, the halfway number is 278 higher than 100 and 278 lower than 656. Therefore, our halfway between answer of 378 above is correct.
