Halfway Between 20 and 422

When you ask "What number is halfway between 20 and 422?" 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=422.

Halfway Between Line

To find the number halfway between 20 and 422, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 20 and 422 into our formula, we get:

(20 + 422)/2 = 221

Thus, the number halfway between 20 and 422 is 221.

To check that our answer is correct, we subtract 20 from 221 and subtract 221 from 422 and compare the two numbers:

221 - 20 = 201
422 - 221 = 201

As you can see, the halfway number is 201 higher than 20 and 201 lower than 422. Therefore, our halfway between answer of 221 above is correct.
