Halfway Between 85 and 669

When you ask "What number is halfway between 85 and 669?" 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=669.

Halfway Between Line

To find the number halfway between 85 and 669, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 85 and 669 into our formula, we get:

(85 + 669)/2 = 377

Thus, the number halfway between 85 and 669 is 377.

To check that our answer is correct, we subtract 85 from 377 and subtract 377 from 669 and compare the two numbers:

377 - 85 = 292
669 - 377 = 292

As you can see, the halfway number is 292 higher than 85 and 292 lower than 669. Therefore, our halfway between answer of 377 above is correct.
