Halfway Between 100 and 818

When you ask "What number is halfway between 100 and 818?" 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=818.

Halfway Between Line

To find the number halfway between 100 and 818, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 818 into our formula, we get:

(100 + 818)/2 = 459

Thus, the number halfway between 100 and 818 is 459.

To check that our answer is correct, we subtract 100 from 459 and subtract 459 from 818 and compare the two numbers:

459 - 100 = 359
818 - 459 = 359

As you can see, the halfway number is 359 higher than 100 and 359 lower than 818. Therefore, our halfway between answer of 459 above is correct.
