Halfway Between 66 and 188

When you ask "What number is halfway between 66 and 188?" 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=188.

Halfway Between Line

To find the number halfway between 66 and 188, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 66 and 188 into our formula, we get:

(66 + 188)/2 = 127

Thus, the number halfway between 66 and 188 is 127.

To check that our answer is correct, we subtract 66 from 127 and subtract 127 from 188 and compare the two numbers:

127 - 66 = 61
188 - 127 = 61

As you can see, the halfway number is 61 higher than 66 and 61 lower than 188. Therefore, our halfway between answer of 127 above is correct.
