Halfway Between 21 and 731

When you ask "What number is halfway between 21 and 731?" 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=731.

Halfway Between Line

To find the number halfway between 21 and 731, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 21 and 731 into our formula, we get:

(21 + 731)/2 = 376

Thus, the number halfway between 21 and 731 is 376.

To check that our answer is correct, we subtract 21 from 376 and subtract 376 from 731 and compare the two numbers:

376 - 21 = 355
731 - 376 = 355

As you can see, the halfway number is 355 higher than 21 and 355 lower than 731. Therefore, our halfway between answer of 376 above is correct.
