Halfway Between 100 and 506

When you ask "What number is halfway between 100 and 506?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=100 and Y=506.

Halfway Between Line

To find the number halfway between 100 and 506, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 506 into our formula, we get:

(100 + 506)/2 = 303

Thus, the number halfway between 100 and 506 is 303.

To check that our answer is correct, we subtract 100 from 303 and subtract 303 from 506 and compare the two numbers:

303 - 100 = 203
506 - 303 = 203

As you can see, the halfway number is 203 higher than 100 and 203 lower than 506. Therefore, our halfway between answer of 303 above is correct.
