Halfway Between 20 and 428

When you ask "What number is halfway between 20 and 428?" 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=428.

Halfway Between Line

To find the number halfway between 20 and 428, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 20 and 428 into our formula, we get:

(20 + 428)/2 = 224

Thus, the number halfway between 20 and 428 is 224.

To check that our answer is correct, we subtract 20 from 224 and subtract 224 from 428 and compare the two numbers:

224 - 20 = 204
428 - 224 = 204

As you can see, the halfway number is 204 higher than 20 and 204 lower than 428. Therefore, our halfway between answer of 224 above is correct.
