Halfway Between 1 and 422

When you ask "What number is halfway between 1 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=1 and Y=422.

Halfway Between Line

To find the number halfway between 1 and 422, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 1 and 422 into our formula, we get:

(1 + 422)/2 = 211.5

Thus, the number halfway between 1 and 422 is 211.5.

To check that our answer is correct, we subtract 1 from 211.5 and subtract 211.5 from 422 and compare the two numbers:

211.5 - 1 = 210.5
422 - 211.5 = 210.5

As you can see, the halfway number is 210.5 higher than 1 and 210.5 lower than 422. Therefore, our halfway between answer of 211.5 above is correct.
