Halfway Between 85 and 697

When you ask "What number is halfway between 85 and 697?" 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=697.

Halfway Between Line

To find the number halfway between 85 and 697, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 85 and 697 into our formula, we get:

(85 + 697)/2 = 391

Thus, the number halfway between 85 and 697 is 391.

To check that our answer is correct, we subtract 85 from 391 and subtract 391 from 697 and compare the two numbers:

391 - 85 = 306
697 - 391 = 306

As you can see, the halfway number is 306 higher than 85 and 306 lower than 697. Therefore, our halfway between answer of 391 above is correct.
