Halfway Between 100 and 540

When you ask "What number is halfway between 100 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=100 and Y=540.

Halfway Between Line

To find the number halfway between 100 and 540, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 540 into our formula, we get:

(100 + 540)/2 = 320

Thus, the number halfway between 100 and 540 is 320.

To check that our answer is correct, we subtract 100 from 320 and subtract 320 from 540 and compare the two numbers:

320 - 100 = 220
540 - 320 = 220

As you can see, the halfway number is 220 higher than 100 and 220 lower than 540. Therefore, our halfway between answer of 320 above is correct.
