Halfway Between 66 and 624

When you ask "What number is halfway between 66 and 624?" 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=624.

Halfway Between Line

To find the number halfway between 66 and 624, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 66 and 624 into our formula, we get:

(66 + 624)/2 = 345

Thus, the number halfway between 66 and 624 is 345.

To check that our answer is correct, we subtract 66 from 345 and subtract 345 from 624 and compare the two numbers:

345 - 66 = 279
624 - 345 = 279

As you can see, the halfway number is 279 higher than 66 and 279 lower than 624. Therefore, our halfway between answer of 345 above is correct.
