Halfway Between 100 and 571

When you ask "What number is halfway between 100 and 571?" 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=571.

Halfway Between Line

To find the number halfway between 100 and 571, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 571 into our formula, we get:

(100 + 571)/2 = 335.5

Thus, the number halfway between 100 and 571 is 335.5.

To check that our answer is correct, we subtract 100 from 335.5 and subtract 335.5 from 571 and compare the two numbers:

335.5 - 100 = 235.5
571 - 335.5 = 235.5

As you can see, the halfway number is 235.5 higher than 100 and 235.5 lower than 571. Therefore, our halfway between answer of 335.5 above is correct.
