Halfway Between 85 and 427

When you ask "What number is halfway between 85 and 427?" 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=427.

Halfway Between Line

To find the number halfway between 85 and 427, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 85 and 427 into our formula, we get:

(85 + 427)/2 = 256

Thus, the number halfway between 85 and 427 is 256.

To check that our answer is correct, we subtract 85 from 256 and subtract 256 from 427 and compare the two numbers:

256 - 85 = 171
427 - 256 = 171

As you can see, the halfway number is 171 higher than 85 and 171 lower than 427. Therefore, our halfway between answer of 256 above is correct.
