Halfway Between 85 and 617

When you ask "What number is halfway between 85 and 617?" 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=617.

Halfway Between Line

To find the number halfway between 85 and 617, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 85 and 617 into our formula, we get:

(85 + 617)/2 = 351

Thus, the number halfway between 85 and 617 is 351.

To check that our answer is correct, we subtract 85 from 351 and subtract 351 from 617 and compare the two numbers:

351 - 85 = 266
617 - 351 = 266

As you can see, the halfway number is 266 higher than 85 and 266 lower than 617. Therefore, our halfway between answer of 351 above is correct.
