Halfway Between 85 and 637

When you ask "What number is halfway between 85 and 637?" 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=637.

Halfway Between Line

To find the number halfway between 85 and 637, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 85 and 637 into our formula, we get:

(85 + 637)/2 = 361

Thus, the number halfway between 85 and 637 is 361.

To check that our answer is correct, we subtract 85 from 361 and subtract 361 from 637 and compare the two numbers:

361 - 85 = 276
637 - 361 = 276

As you can see, the halfway number is 276 higher than 85 and 276 lower than 637. Therefore, our halfway between answer of 361 above is correct.
