Halfway Between 20 and 456

When you ask "What number is halfway between 20 and 456?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=20 and Y=456.

Halfway Between Line

To find the number halfway between 20 and 456, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 20 and 456 into our formula, we get:

(20 + 456)/2 = 238

Thus, the number halfway between 20 and 456 is 238.

To check that our answer is correct, we subtract 20 from 238 and subtract 238 from 456 and compare the two numbers:

238 - 20 = 218
456 - 238 = 218

As you can see, the halfway number is 218 higher than 20 and 218 lower than 456. Therefore, our halfway between answer of 238 above is correct.
