Halfway Between 100 and 216

When you ask "What number is halfway between 100 and 216?" 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=216.

Halfway Between Line

To find the number halfway between 100 and 216, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 216 into our formula, we get:

(100 + 216)/2 = 158

Thus, the number halfway between 100 and 216 is 158.

To check that our answer is correct, we subtract 100 from 158 and subtract 158 from 216 and compare the two numbers:

158 - 100 = 58
216 - 158 = 58

As you can see, the halfway number is 58 higher than 100 and 58 lower than 216. Therefore, our halfway between answer of 158 above is correct.
