Halfway Between 66 and 275

When you ask "What number is halfway between 66 and 275?" 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=275.

Halfway Between Line

To find the number halfway between 66 and 275, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 66 and 275 into our formula, we get:

(66 + 275)/2 = 170.5

Thus, the number halfway between 66 and 275 is 170.5.

To check that our answer is correct, we subtract 66 from 170.5 and subtract 170.5 from 275 and compare the two numbers:

170.5 - 66 = 104.5
275 - 170.5 = 104.5

As you can see, the halfway number is 104.5 higher than 66 and 104.5 lower than 275. Therefore, our halfway between answer of 170.5 above is correct.
