Halfway Between 21 and 959

When you ask "What number is halfway between 21 and 959?" 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=959.

Halfway Between Line

To find the number halfway between 21 and 959, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 21 and 959 into our formula, we get:

(21 + 959)/2 = 490

Thus, the number halfway between 21 and 959 is 490.

To check that our answer is correct, we subtract 21 from 490 and subtract 490 from 959 and compare the two numbers:

490 - 21 = 469
959 - 490 = 469

As you can see, the halfway number is 469 higher than 21 and 469 lower than 959. Therefore, our halfway between answer of 490 above is correct.
