Halfway Between 45 and 490

When you ask "What number is halfway between 45 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=45 and Y=490.

Halfway Between Line

To find the number halfway between 45 and 490, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 45 and 490 into our formula, we get:

(45 + 490)/2 = 267.5

Thus, the number halfway between 45 and 490 is 267.5.

To check that our answer is correct, we subtract 45 from 267.5 and subtract 267.5 from 490 and compare the two numbers:

267.5 - 45 = 222.5
490 - 267.5 = 222.5

As you can see, the halfway number is 222.5 higher than 45 and 222.5 lower than 490. Therefore, our halfway between answer of 267.5 above is correct.
