Halfway Between 15 and 363

When you ask "What number is halfway between 15 and 363?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=15 and Y=363.

Halfway Between Line

To find the number halfway between 15 and 363, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 15 and 363 into our formula, we get:

(15 + 363)/2 = 189

Thus, the number halfway between 15 and 363 is 189.

To check that our answer is correct, we subtract 15 from 189 and subtract 189 from 363 and compare the two numbers:

189 - 15 = 174
363 - 189 = 174

As you can see, the halfway number is 174 higher than 15 and 174 lower than 363. Therefore, our halfway between answer of 189 above is correct.
