Halfway Between 85 and 671

When you ask "What number is halfway between 85 and 671?" 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=671.

Halfway Between Line

To find the number halfway between 85 and 671, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 85 and 671 into our formula, we get:

(85 + 671)/2 = 378

Thus, the number halfway between 85 and 671 is 378.

To check that our answer is correct, we subtract 85 from 378 and subtract 378 from 671 and compare the two numbers:

378 - 85 = 293
671 - 378 = 293

As you can see, the halfway number is 293 higher than 85 and 293 lower than 671. Therefore, our halfway between answer of 378 above is correct.
