Halfway Between 57 and 490

When you ask "What number is halfway between 57 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=57 and Y=490.

Halfway Between Line

To find the number halfway between 57 and 490, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 57 and 490 into our formula, we get:

(57 + 490)/2 = 273.5

Thus, the number halfway between 57 and 490 is 273.5.

To check that our answer is correct, we subtract 57 from 273.5 and subtract 273.5 from 490 and compare the two numbers:

273.5 - 57 = 216.5
490 - 273.5 = 216.5

As you can see, the halfway number is 216.5 higher than 57 and 216.5 lower than 490. Therefore, our halfway between answer of 273.5 above is correct.
