Halfway Between 85 and 401

When you ask "What number is halfway between 85 and 401?" 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=401.

Halfway Between Line

To find the number halfway between 85 and 401, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 85 and 401 into our formula, we get:

(85 + 401)/2 = 243

Thus, the number halfway between 85 and 401 is 243.

To check that our answer is correct, we subtract 85 from 243 and subtract 243 from 401 and compare the two numbers:

243 - 85 = 158
401 - 243 = 158

As you can see, the halfway number is 158 higher than 85 and 158 lower than 401. Therefore, our halfway between answer of 243 above is correct.
