Halfway Between 21 and 369

When you ask "What number is halfway between 21 and 369?" 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=369.

Halfway Between Line

To find the number halfway between 21 and 369, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 21 and 369 into our formula, we get:

(21 + 369)/2 = 195

Thus, the number halfway between 21 and 369 is 195.

To check that our answer is correct, we subtract 21 from 195 and subtract 195 from 369 and compare the two numbers:

195 - 21 = 174
369 - 195 = 174

As you can see, the halfway number is 174 higher than 21 and 174 lower than 369. Therefore, our halfway between answer of 195 above is correct.
