Halfway Between 1 and 506

When you ask "What number is halfway between 1 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=1 and Y=506.

Halfway Between Line

To find the number halfway between 1 and 506, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 1 and 506 into our formula, we get:

(1 + 506)/2 = 253.5

Thus, the number halfway between 1 and 506 is 253.5.

To check that our answer is correct, we subtract 1 from 253.5 and subtract 253.5 from 506 and compare the two numbers:

253.5 - 1 = 252.5
506 - 253.5 = 252.5

As you can see, the halfway number is 252.5 higher than 1 and 252.5 lower than 506. Therefore, our halfway between answer of 253.5 above is correct.
