Halfway Between 66 and 200

When you ask "What number is halfway between 66 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=66 and Y=200.

Halfway Between Line

To find the number halfway between 66 and 200, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 66 and 200 into our formula, we get:

(66 + 200)/2 = 133

Thus, the number halfway between 66 and 200 is 133.

To check that our answer is correct, we subtract 66 from 133 and subtract 133 from 200 and compare the two numbers:

133 - 66 = 67
200 - 133 = 67

As you can see, the halfway number is 67 higher than 66 and 67 lower than 200. Therefore, our halfway between answer of 133 above is correct.
