Halfway Between 85 and 540

When you ask "What number is halfway between 85 and 540?" 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=540.

Halfway Between Line

To find the number halfway between 85 and 540, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 85 and 540 into our formula, we get:

(85 + 540)/2 = 312.5

Thus, the number halfway between 85 and 540 is 312.5.

To check that our answer is correct, we subtract 85 from 312.5 and subtract 312.5 from 540 and compare the two numbers:

312.5 - 85 = 227.5
540 - 312.5 = 227.5

As you can see, the halfway number is 227.5 higher than 85 and 227.5 lower than 540. Therefore, our halfway between answer of 312.5 above is correct.
