Halfway Between 1 and 505

When you ask "What number is halfway between 1 and 505?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=1 and Y=505.

Halfway Between Line

To find the number halfway between 1 and 505, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 1 and 505 into our formula, we get:

(1 + 505)/2 = 253

Thus, the number halfway between 1 and 505 is 253.

To check that our answer is correct, we subtract 1 from 253 and subtract 253 from 505 and compare the two numbers:

253 - 1 = 252
505 - 253 = 252

As you can see, the halfway number is 252 higher than 1 and 252 lower than 505. Therefore, our halfway between answer of 253 above is correct.
