Halfway Between 66 and 650

When you ask "What number is halfway between 66 and 650?" 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=650.

Halfway Between Line

To find the number halfway between 66 and 650, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 66 and 650 into our formula, we get:

(66 + 650)/2 = 358

Thus, the number halfway between 66 and 650 is 358.

To check that our answer is correct, we subtract 66 from 358 and subtract 358 from 650 and compare the two numbers:

358 - 66 = 292
650 - 358 = 292

As you can see, the halfway number is 292 higher than 66 and 292 lower than 650. Therefore, our halfway between answer of 358 above is correct.
