Halfway Between 30 and 505

When you ask "What number is halfway between 30 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=30 and Y=505.

Halfway Between Line

To find the number halfway between 30 and 505, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 30 and 505 into our formula, we get:

(30 + 505)/2 = 267.5

Thus, the number halfway between 30 and 505 is 267.5.

To check that our answer is correct, we subtract 30 from 267.5 and subtract 267.5 from 505 and compare the two numbers:

267.5 - 30 = 237.5
505 - 267.5 = 237.5

As you can see, the halfway number is 237.5 higher than 30 and 237.5 lower than 505. Therefore, our halfway between answer of 267.5 above is correct.
