Halfway Between 90 and 198

When you ask "What number is halfway between 90 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=90 and Y=198.

Halfway Between Line

To find the number halfway between 90 and 198, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 90 and 198 into our formula, we get:

(90 + 198)/2 = 144

Thus, the number halfway between 90 and 198 is 144.

To check that our answer is correct, we subtract 90 from 144 and subtract 144 from 198 and compare the two numbers:

144 - 90 = 54
198 - 144 = 54

As you can see, the halfway number is 54 higher than 90 and 54 lower than 198. Therefore, our halfway between answer of 144 above is correct.
