Halfway Between 66 and 552

When you ask "What number is halfway between 66 and 552?" 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=552.

Halfway Between Line

To find the number halfway between 66 and 552, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 66 and 552 into our formula, we get:

(66 + 552)/2 = 309

Thus, the number halfway between 66 and 552 is 309.

To check that our answer is correct, we subtract 66 from 309 and subtract 309 from 552 and compare the two numbers:

309 - 66 = 243
552 - 309 = 243

As you can see, the halfway number is 243 higher than 66 and 243 lower than 552. Therefore, our halfway between answer of 309 above is correct.
