Halfway Between 85 and 674

When you ask "What number is halfway between 85 and 674?" 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=674.

Halfway Between Line

To find the number halfway between 85 and 674, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 85 and 674 into our formula, we get:

(85 + 674)/2 = 379.5

Thus, the number halfway between 85 and 674 is 379.5.

To check that our answer is correct, we subtract 85 from 379.5 and subtract 379.5 from 674 and compare the two numbers:

379.5 - 85 = 294.5
674 - 379.5 = 294.5

As you can see, the halfway number is 294.5 higher than 85 and 294.5 lower than 674. Therefore, our halfway between answer of 379.5 above is correct.
