Halfway Between 85 and 259

When you ask "What number is halfway between 85 and 259?" 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=259.

Halfway Between Line

To find the number halfway between 85 and 259, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 85 and 259 into our formula, we get:

(85 + 259)/2 = 172

Thus, the number halfway between 85 and 259 is 172.

To check that our answer is correct, we subtract 85 from 172 and subtract 172 from 259 and compare the two numbers:

172 - 85 = 87
259 - 172 = 87

As you can see, the halfway number is 87 higher than 85 and 87 lower than 259. Therefore, our halfway between answer of 172 above is correct.
