Halfway Between 30 and 422

When you ask "What number is halfway between 30 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=30 and Y=422.

Halfway Between Line

To find the number halfway between 30 and 422, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 30 and 422 into our formula, we get:

(30 + 422)/2 = 226

Thus, the number halfway between 30 and 422 is 226.

To check that our answer is correct, we subtract 30 from 226 and subtract 226 from 422 and compare the two numbers:

226 - 30 = 196
422 - 226 = 196

As you can see, the halfway number is 196 higher than 30 and 196 lower than 422. Therefore, our halfway between answer of 226 above is correct.
