Halfway Between 77 and 200

When you ask "What number is halfway between 77 and 200?" 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=200.

Halfway Between Line

To find the number halfway between 77 and 200, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 77 and 200 into our formula, we get:

(77 + 200)/2 = 138.5

Thus, the number halfway between 77 and 200 is 138.5.

To check that our answer is correct, we subtract 77 from 138.5 and subtract 138.5 from 200 and compare the two numbers:

138.5 - 77 = 61.5
200 - 138.5 = 61.5

As you can see, the halfway number is 61.5 higher than 77 and 61.5 lower than 200. Therefore, our halfway between answer of 138.5 above is correct.
