Halfway Between 100 and 490

When you ask "What number is halfway between 100 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=100 and Y=490.

Halfway Between Line

To find the number halfway between 100 and 490, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 490 into our formula, we get:

(100 + 490)/2 = 295

Thus, the number halfway between 100 and 490 is 295.

To check that our answer is correct, we subtract 100 from 295 and subtract 295 from 490 and compare the two numbers:

295 - 100 = 195
490 - 295 = 195

As you can see, the halfway number is 195 higher than 100 and 195 lower than 490. Therefore, our halfway between answer of 295 above is correct.
