Halfway Between 100 and 672

When you ask "What number is halfway between 100 and 672?" 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=672.

Halfway Between Line

To find the number halfway between 100 and 672, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 672 into our formula, we get:

(100 + 672)/2 = 386

Thus, the number halfway between 100 and 672 is 386.

To check that our answer is correct, we subtract 100 from 386 and subtract 386 from 672 and compare the two numbers:

386 - 100 = 286
672 - 386 = 286

As you can see, the halfway number is 286 higher than 100 and 286 lower than 672. Therefore, our halfway between answer of 386 above is correct.
