Halfway Between 70 and 505

When you ask "What number is halfway between 70 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=70 and Y=505.

Halfway Between Line

To find the number halfway between 70 and 505, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 70 and 505 into our formula, we get:

(70 + 505)/2 = 287.5

Thus, the number halfway between 70 and 505 is 287.5.

To check that our answer is correct, we subtract 70 from 287.5 and subtract 287.5 from 505 and compare the two numbers:

287.5 - 70 = 217.5
505 - 287.5 = 217.5

As you can see, the halfway number is 217.5 higher than 70 and 217.5 lower than 505. Therefore, our halfway between answer of 287.5 above is correct.
