Halfway Between 21 and 49

When you ask "What number is halfway between 21 and 49?" 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=49.

Halfway Between Line

To find the number halfway between 21 and 49, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 21 and 49 into our formula, we get:

(21 + 49)/2 = 35

Thus, the number halfway between 21 and 49 is 35.

To check that our answer is correct, we subtract 21 from 35 and subtract 35 from 49 and compare the two numbers:

35 - 21 = 14
49 - 35 = 14

As you can see, the halfway number is 14 higher than 21 and 14 lower than 49. Therefore, our halfway between answer of 35 above is correct.
