Halfway Between 85 and 615

When you ask "What number is halfway between 85 and 615?" 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=615.

Halfway Between Line

To find the number halfway between 85 and 615, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 85 and 615 into our formula, we get:

(85 + 615)/2 = 350

Thus, the number halfway between 85 and 615 is 350.

To check that our answer is correct, we subtract 85 from 350 and subtract 350 from 615 and compare the two numbers:

350 - 85 = 265
615 - 350 = 265

As you can see, the halfway number is 265 higher than 85 and 265 lower than 615. Therefore, our halfway between answer of 350 above is correct.
