Halfway Between 85 and 710

When you ask "What number is halfway between 85 and 710?" 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=710.

Halfway Between Line

To find the number halfway between 85 and 710, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 85 and 710 into our formula, we get:

(85 + 710)/2 = 397.5

Thus, the number halfway between 85 and 710 is 397.5.

To check that our answer is correct, we subtract 85 from 397.5 and subtract 397.5 from 710 and compare the two numbers:

397.5 - 85 = 312.5
710 - 397.5 = 312.5

As you can see, the halfway number is 312.5 higher than 85 and 312.5 lower than 710. Therefore, our halfway between answer of 397.5 above is correct.
