Halfway Between 3 and 557

When you ask "What number is halfway between 3 and 557?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=3 and Y=557.

Halfway Between Line

To find the number halfway between 3 and 557, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 3 and 557 into our formula, we get:

(3 + 557)/2 = 280

Thus, the number halfway between 3 and 557 is 280.

To check that our answer is correct, we subtract 3 from 280 and subtract 280 from 557 and compare the two numbers:

280 - 3 = 277
557 - 280 = 277

As you can see, the halfway number is 277 higher than 3 and 277 lower than 557. Therefore, our halfway between answer of 280 above is correct.
