Halfway Between 55 and 543

When you ask "What number is halfway between 55 and 543?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=55 and Y=543.

Halfway Between Line

To find the number halfway between 55 and 543, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 55 and 543 into our formula, we get:

(55 + 543)/2 = 299

Thus, the number halfway between 55 and 543 is 299.

To check that our answer is correct, we subtract 55 from 299 and subtract 299 from 543 and compare the two numbers:

299 - 55 = 244
543 - 299 = 244

As you can see, the halfway number is 244 higher than 55 and 244 lower than 543. Therefore, our halfway between answer of 299 above is correct.
