Halfway Between 66 and 490

When you ask "What number is halfway between 66 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=66 and Y=490.

Halfway Between Line

To find the number halfway between 66 and 490, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 66 and 490 into our formula, we get:

(66 + 490)/2 = 278

Thus, the number halfway between 66 and 490 is 278.

To check that our answer is correct, we subtract 66 from 278 and subtract 278 from 490 and compare the two numbers:

278 - 66 = 212
490 - 278 = 212

As you can see, the halfway number is 212 higher than 66 and 212 lower than 490. Therefore, our halfway between answer of 278 above is correct.
