Halfway Between 77 and 198

When you ask "What number is halfway between 77 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=77 and Y=198.

Halfway Between Line

To find the number halfway between 77 and 198, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 77 and 198 into our formula, we get:

(77 + 198)/2 = 137.5

Thus, the number halfway between 77 and 198 is 137.5.

To check that our answer is correct, we subtract 77 from 137.5 and subtract 137.5 from 198 and compare the two numbers:

137.5 - 77 = 60.5
198 - 137.5 = 60.5

As you can see, the halfway number is 60.5 higher than 77 and 60.5 lower than 198. Therefore, our halfway between answer of 137.5 above is correct.
