Halfway Between 85 and 538

When you ask "What number is halfway between 85 and 538?" 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=538.

Halfway Between Line

To find the number halfway between 85 and 538, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 85 and 538 into our formula, we get:

(85 + 538)/2 = 311.5

Thus, the number halfway between 85 and 538 is 311.5.

To check that our answer is correct, we subtract 85 from 311.5 and subtract 311.5 from 538 and compare the two numbers:

311.5 - 85 = 226.5
538 - 311.5 = 226.5

As you can see, the halfway number is 226.5 higher than 85 and 226.5 lower than 538. Therefore, our halfway between answer of 311.5 above is correct.
