Halfway Between 85 and 545

When you ask "What number is halfway between 85 and 545?" 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=545.

Halfway Between Line

To find the number halfway between 85 and 545, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 85 and 545 into our formula, we get:

(85 + 545)/2 = 315

Thus, the number halfway between 85 and 545 is 315.

To check that our answer is correct, we subtract 85 from 315 and subtract 315 from 545 and compare the two numbers:

315 - 85 = 230
545 - 315 = 230

As you can see, the halfway number is 230 higher than 85 and 230 lower than 545. Therefore, our halfway between answer of 315 above is correct.
