Halfway Between 100 and 198

When you ask "What number is halfway between 100 and 198?" 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=198.

Halfway Between Line

To find the number halfway between 100 and 198, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 198 into our formula, we get:

(100 + 198)/2 = 149

Thus, the number halfway between 100 and 198 is 149.

To check that our answer is correct, we subtract 100 from 149 and subtract 149 from 198 and compare the two numbers:

149 - 100 = 49
198 - 149 = 49

As you can see, the halfway number is 49 higher than 100 and 49 lower than 198. Therefore, our halfway between answer of 149 above is correct.
