Halfway Between 89 and 198

When you ask "What number is halfway between 89 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=89 and Y=198.

Halfway Between Line

To find the number halfway between 89 and 198, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 89 and 198 into our formula, we get:

(89 + 198)/2 = 143.5

Thus, the number halfway between 89 and 198 is 143.5.

To check that our answer is correct, we subtract 89 from 143.5 and subtract 143.5 from 198 and compare the two numbers:

143.5 - 89 = 54.5
198 - 143.5 = 54.5

As you can see, the halfway number is 54.5 higher than 89 and 54.5 lower than 198. Therefore, our halfway between answer of 143.5 above is correct.
