Halfway Between 100 and 312

When you ask "What number is halfway between 100 and 312?" 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=312.

Halfway Between Line

To find the number halfway between 100 and 312, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 312 into our formula, we get:

(100 + 312)/2 = 206

Thus, the number halfway between 100 and 312 is 206.

To check that our answer is correct, we subtract 100 from 206 and subtract 206 from 312 and compare the two numbers:

206 - 100 = 106
312 - 206 = 106

As you can see, the halfway number is 106 higher than 100 and 106 lower than 312. Therefore, our halfway between answer of 206 above is correct.
