Halfway Between 66 and 572

When you ask "What number is halfway between 66 and 572?" 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=572.

Halfway Between Line

To find the number halfway between 66 and 572, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 66 and 572 into our formula, we get:

(66 + 572)/2 = 319

Thus, the number halfway between 66 and 572 is 319.

To check that our answer is correct, we subtract 66 from 319 and subtract 319 from 572 and compare the two numbers:

319 - 66 = 253
572 - 319 = 253

As you can see, the halfway number is 253 higher than 66 and 253 lower than 572. Therefore, our halfway between answer of 319 above is correct.
