Halfway Between 20 and 458

When you ask "What number is halfway between 20 and 458?" 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=458.

Halfway Between Line

To find the number halfway between 20 and 458, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 20 and 458 into our formula, we get:

(20 + 458)/2 = 239

Thus, the number halfway between 20 and 458 is 239.

To check that our answer is correct, we subtract 20 from 239 and subtract 239 from 458 and compare the two numbers:

239 - 20 = 219
458 - 239 = 219

As you can see, the halfway number is 219 higher than 20 and 219 lower than 458. Therefore, our halfway between answer of 239 above is correct.
