Halfway Between 21 and 901

When you ask "What number is halfway between 21 and 901?" 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=901.

Halfway Between Line

To find the number halfway between 21 and 901, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 21 and 901 into our formula, we get:

(21 + 901)/2 = 461

Thus, the number halfway between 21 and 901 is 461.

To check that our answer is correct, we subtract 21 from 461 and subtract 461 from 901 and compare the two numbers:

461 - 21 = 440
901 - 461 = 440

As you can see, the halfway number is 440 higher than 21 and 440 lower than 901. Therefore, our halfway between answer of 461 above is correct.
