Halfway Between 66 and 649

When you ask "What number is halfway between 66 and 649?" 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=649.

Halfway Between Line

To find the number halfway between 66 and 649, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 66 and 649 into our formula, we get:

(66 + 649)/2 = 357.5

Thus, the number halfway between 66 and 649 is 357.5.

To check that our answer is correct, we subtract 66 from 357.5 and subtract 357.5 from 649 and compare the two numbers:

357.5 - 66 = 291.5
649 - 357.5 = 291.5

As you can see, the halfway number is 291.5 higher than 66 and 291.5 lower than 649. Therefore, our halfway between answer of 357.5 above is correct.
