Halfway Between 85 and 422

When you ask "What number is halfway between 85 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=85 and Y=422.

Halfway Between Line

To find the number halfway between 85 and 422, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 85 and 422 into our formula, we get:

(85 + 422)/2 = 253.5

Thus, the number halfway between 85 and 422 is 253.5.

To check that our answer is correct, we subtract 85 from 253.5 and subtract 253.5 from 422 and compare the two numbers:

253.5 - 85 = 168.5
422 - 253.5 = 168.5

As you can see, the halfway number is 168.5 higher than 85 and 168.5 lower than 422. Therefore, our halfway between answer of 253.5 above is correct.
