Halfway Between 20 and 495

When you ask "What number is halfway between 20 and 495?" 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=495.

Halfway Between Line

To find the number halfway between 20 and 495, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 20 and 495 into our formula, we get:

(20 + 495)/2 = 257.5

Thus, the number halfway between 20 and 495 is 257.5.

To check that our answer is correct, we subtract 20 from 257.5 and subtract 257.5 from 495 and compare the two numbers:

257.5 - 20 = 237.5
495 - 257.5 = 237.5

As you can see, the halfway number is 237.5 higher than 20 and 237.5 lower than 495. Therefore, our halfway between answer of 257.5 above is correct.
