Halfway Between 27 and 198

When you ask "What number is halfway between 27 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=27 and Y=198.

Halfway Between Line

To find the number halfway between 27 and 198, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 27 and 198 into our formula, we get:

(27 + 198)/2 = 112.5

Thus, the number halfway between 27 and 198 is 112.5.

To check that our answer is correct, we subtract 27 from 112.5 and subtract 112.5 from 198 and compare the two numbers:

112.5 - 27 = 85.5
198 - 112.5 = 85.5

As you can see, the halfway number is 85.5 higher than 27 and 85.5 lower than 198. Therefore, our halfway between answer of 112.5 above is correct.
