Halfway Between 66 and 307

When you ask "What number is halfway between 66 and 307?" 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=307.

Halfway Between Line

To find the number halfway between 66 and 307, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 66 and 307 into our formula, we get:

(66 + 307)/2 = 186.5

Thus, the number halfway between 66 and 307 is 186.5.

To check that our answer is correct, we subtract 66 from 186.5 and subtract 186.5 from 307 and compare the two numbers:

186.5 - 66 = 120.5
307 - 186.5 = 120.5

As you can see, the halfway number is 120.5 higher than 66 and 120.5 lower than 307. Therefore, our halfway between answer of 186.5 above is correct.
