Halfway Between 66 and 199

When you ask "What number is halfway between 66 and 199?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=66 and Y=199.

Halfway Between Line

To find the number halfway between 66 and 199, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 66 and 199 into our formula, we get:

(66 + 199)/2 = 132.5

Thus, the number halfway between 66 and 199 is 132.5.

To check that our answer is correct, we subtract 66 from 132.5 and subtract 132.5 from 199 and compare the two numbers:

132.5 - 66 = 66.5
199 - 132.5 = 66.5

As you can see, the halfway number is 66.5 higher than 66 and 66.5 lower than 199. Therefore, our halfway between answer of 132.5 above is correct.
