Halfway Between 20 and 651

When you ask "What number is halfway between 20 and 651?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=20 and Y=651.

Halfway Between Line

To find the number halfway between 20 and 651, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 20 and 651 into our formula, we get:

(20 + 651)/2 = 335.5

Thus, the number halfway between 20 and 651 is 335.5.

To check that our answer is correct, we subtract 20 from 335.5 and subtract 335.5 from 651 and compare the two numbers:

335.5 - 20 = 315.5
651 - 335.5 = 315.5

As you can see, the halfway number is 315.5 higher than 20 and 315.5 lower than 651. Therefore, our halfway between answer of 335.5 above is correct.
