Halfway Between 100 and 208

When you ask "What number is halfway between 100 and 208?" 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=208.

Halfway Between Line

To find the number halfway between 100 and 208, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 208 into our formula, we get:

(100 + 208)/2 = 154

Thus, the number halfway between 100 and 208 is 154.

To check that our answer is correct, we subtract 100 from 154 and subtract 154 from 208 and compare the two numbers:

154 - 100 = 54
208 - 154 = 54

As you can see, the halfway number is 54 higher than 100 and 54 lower than 208. Therefore, our halfway between answer of 154 above is correct.
