Halfway Between 21 and 353

When you ask "What number is halfway between 21 and 353?" 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=353.

Halfway Between Line

To find the number halfway between 21 and 353, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 21 and 353 into our formula, we get:

(21 + 353)/2 = 187

Thus, the number halfway between 21 and 353 is 187.

To check that our answer is correct, we subtract 21 from 187 and subtract 187 from 353 and compare the two numbers:

187 - 21 = 166
353 - 187 = 166

As you can see, the halfway number is 166 higher than 21 and 166 lower than 353. Therefore, our halfway between answer of 187 above is correct.
