Halfway Between 9 and 198

When you ask "What number is halfway between 9 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=9 and Y=198.

Halfway Between Line

To find the number halfway between 9 and 198, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 9 and 198 into our formula, we get:

(9 + 198)/2 = 103.5

Thus, the number halfway between 9 and 198 is 103.5.

To check that our answer is correct, we subtract 9 from 103.5 and subtract 103.5 from 198 and compare the two numbers:

103.5 - 9 = 94.5
198 - 103.5 = 94.5

As you can see, the halfway number is 94.5 higher than 9 and 94.5 lower than 198. Therefore, our halfway between answer of 103.5 above is correct.
