Halfway Between 85 and 735

When you ask "What number is halfway between 85 and 735?" 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=735.

Halfway Between Line

To find the number halfway between 85 and 735, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 85 and 735 into our formula, we get:

(85 + 735)/2 = 410

Thus, the number halfway between 85 and 735 is 410.

To check that our answer is correct, we subtract 85 from 410 and subtract 410 from 735 and compare the two numbers:

410 - 85 = 325
735 - 410 = 325

As you can see, the halfway number is 325 higher than 85 and 325 lower than 735. Therefore, our halfway between answer of 410 above is correct.
