Halfway Between 100 and 504

When you ask "What number is halfway between 100 and 504?" 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=504.

Halfway Between Line

To find the number halfway between 100 and 504, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 504 into our formula, we get:

(100 + 504)/2 = 302

Thus, the number halfway between 100 and 504 is 302.

To check that our answer is correct, we subtract 100 from 302 and subtract 302 from 504 and compare the two numbers:

302 - 100 = 202
504 - 302 = 202

As you can see, the halfway number is 202 higher than 100 and 202 lower than 504. Therefore, our halfway between answer of 302 above is correct.
