Halfway Between 66 and 660

When you ask "What number is halfway between 66 and 660?" 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=660.

Halfway Between Line

To find the number halfway between 66 and 660, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 66 and 660 into our formula, we get:

(66 + 660)/2 = 363

Thus, the number halfway between 66 and 660 is 363.

To check that our answer is correct, we subtract 66 from 363 and subtract 363 from 660 and compare the two numbers:

363 - 66 = 297
660 - 363 = 297

As you can see, the halfway number is 297 higher than 66 and 297 lower than 660. Therefore, our halfway between answer of 363 above is correct.
