Halfway Between 5 and 515

When you ask "What number is halfway between 5 and 515?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=5 and Y=515.

Halfway Between Line

To find the number halfway between 5 and 515, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 5 and 515 into our formula, we get:

(5 + 515)/2 = 260

Thus, the number halfway between 5 and 515 is 260.

To check that our answer is correct, we subtract 5 from 260 and subtract 260 from 515 and compare the two numbers:

260 - 5 = 255
515 - 260 = 255

As you can see, the halfway number is 255 higher than 5 and 255 lower than 515. Therefore, our halfway between answer of 260 above is correct.
