Halfway Between 15 and 273

When you ask "What number is halfway between 15 and 273?" 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=273.

Halfway Between Line

To find the number halfway between 15 and 273, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 15 and 273 into our formula, we get:

(15 + 273)/2 = 144

Thus, the number halfway between 15 and 273 is 144.

To check that our answer is correct, we subtract 15 from 144 and subtract 144 from 273 and compare the two numbers:

144 - 15 = 129
273 - 144 = 129

As you can see, the halfway number is 129 higher than 15 and 129 lower than 273. Therefore, our halfway between answer of 144 above is correct.
