Halfway Between 66 and 634

When you ask "What number is halfway between 66 and 634?" 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=634.

Halfway Between Line

To find the number halfway between 66 and 634, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 66 and 634 into our formula, we get:

(66 + 634)/2 = 350

Thus, the number halfway between 66 and 634 is 350.

To check that our answer is correct, we subtract 66 from 350 and subtract 350 from 634 and compare the two numbers:

350 - 66 = 284
634 - 350 = 284

As you can see, the halfway number is 284 higher than 66 and 284 lower than 634. Therefore, our halfway between answer of 350 above is correct.
