Halfway Between 12 and 398

When you ask "What number is halfway between 12 and 398?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=12 and Y=398.

Halfway Between Line

To find the number halfway between 12 and 398, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 12 and 398 into our formula, we get:

(12 + 398)/2 = 205

Thus, the number halfway between 12 and 398 is 205.

To check that our answer is correct, we subtract 12 from 205 and subtract 205 from 398 and compare the two numbers:

205 - 12 = 193
398 - 205 = 193

As you can see, the halfway number is 193 higher than 12 and 193 lower than 398. Therefore, our halfway between answer of 205 above is correct.
