Halfway Between 20 and 424

When you ask "What number is halfway between 20 and 424?" 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=424.

Halfway Between Line

To find the number halfway between 20 and 424, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 20 and 424 into our formula, we get:

(20 + 424)/2 = 222

Thus, the number halfway between 20 and 424 is 222.

To check that our answer is correct, we subtract 20 from 222 and subtract 222 from 424 and compare the two numbers:

222 - 20 = 202
424 - 222 = 202

As you can see, the halfway number is 202 higher than 20 and 202 lower than 424. Therefore, our halfway between answer of 222 above is correct.
