Halfway Between 66 and 204

When you ask "What number is halfway between 66 and 204?" 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=204.

Halfway Between Line

To find the number halfway between 66 and 204, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 66 and 204 into our formula, we get:

(66 + 204)/2 = 135

Thus, the number halfway between 66 and 204 is 135.

To check that our answer is correct, we subtract 66 from 135 and subtract 135 from 204 and compare the two numbers:

135 - 66 = 69
204 - 135 = 69

As you can see, the halfway number is 69 higher than 66 and 69 lower than 204. Therefore, our halfway between answer of 135 above is correct.
