Halfway Between 51 and 520

When you ask "What number is halfway between 51 and 520?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=51 and Y=520.

Halfway Between Line

To find the number halfway between 51 and 520, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 51 and 520 into our formula, we get:

(51 + 520)/2 = 285.5

Thus, the number halfway between 51 and 520 is 285.5.

To check that our answer is correct, we subtract 51 from 285.5 and subtract 285.5 from 520 and compare the two numbers:

285.5 - 51 = 234.5
520 - 285.5 = 234.5

As you can see, the halfway number is 234.5 higher than 51 and 234.5 lower than 520. Therefore, our halfway between answer of 285.5 above is correct.
