Halfway Between 4 and 422

When you ask "What number is halfway between 4 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=4 and Y=422.

Halfway Between Line

To find the number halfway between 4 and 422, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 4 and 422 into our formula, we get:

(4 + 422)/2 = 213

Thus, the number halfway between 4 and 422 is 213.

To check that our answer is correct, we subtract 4 from 213 and subtract 213 from 422 and compare the two numbers:

213 - 4 = 209
422 - 213 = 209

As you can see, the halfway number is 209 higher than 4 and 209 lower than 422. Therefore, our halfway between answer of 213 above is correct.
