Halfway Between 85 and 257

When you ask "What number is halfway between 85 and 257?" 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=257.

Halfway Between Line

To find the number halfway between 85 and 257, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 85 and 257 into our formula, we get:

(85 + 257)/2 = 171

Thus, the number halfway between 85 and 257 is 171.

To check that our answer is correct, we subtract 85 from 171 and subtract 171 from 257 and compare the two numbers:

171 - 85 = 86
257 - 171 = 86

As you can see, the halfway number is 86 higher than 85 and 86 lower than 257. Therefore, our halfway between answer of 171 above is correct.
