Halfway Between 100 and 418

When you ask "What number is halfway between 100 and 418?" 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=418.

Halfway Between Line

To find the number halfway between 100 and 418, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 418 into our formula, we get:

(100 + 418)/2 = 259

Thus, the number halfway between 100 and 418 is 259.

To check that our answer is correct, we subtract 100 from 259 and subtract 259 from 418 and compare the two numbers:

259 - 100 = 159
418 - 259 = 159

As you can see, the halfway number is 159 higher than 100 and 159 lower than 418. Therefore, our halfway between answer of 259 above is correct.
