Halfway Between 21 and 719

When you ask "What number is halfway between 21 and 719?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=21 and Y=719.

Halfway Between Line

To find the number halfway between 21 and 719, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 21 and 719 into our formula, we get:

(21 + 719)/2 = 370

Thus, the number halfway between 21 and 719 is 370.

To check that our answer is correct, we subtract 21 from 370 and subtract 370 from 719 and compare the two numbers:

370 - 21 = 349
719 - 370 = 349

As you can see, the halfway number is 349 higher than 21 and 349 lower than 719. Therefore, our halfway between answer of 370 above is correct.
