Halfway Between 100 and 718

When you ask "What number is halfway between 100 and 718?" 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=718.

Halfway Between Line

To find the number halfway between 100 and 718, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 718 into our formula, we get:

(100 + 718)/2 = 409

Thus, the number halfway between 100 and 718 is 409.

To check that our answer is correct, we subtract 100 from 409 and subtract 409 from 718 and compare the two numbers:

409 - 100 = 309
718 - 409 = 309

As you can see, the halfway number is 309 higher than 100 and 309 lower than 718. Therefore, our halfway between answer of 409 above is correct.
