Halfway Between 30 and 490

When you ask "What number is halfway between 30 and 490?" 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=490.

Halfway Between Line

To find the number halfway between 30 and 490, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 30 and 490 into our formula, we get:

(30 + 490)/2 = 260

Thus, the number halfway between 30 and 490 is 260.

To check that our answer is correct, we subtract 30 from 260 and subtract 260 from 490 and compare the two numbers:

260 - 30 = 230
490 - 260 = 230

As you can see, the halfway number is 230 higher than 30 and 230 lower than 490. Therefore, our halfway between answer of 260 above is correct.
