Halfway Between 15 and 545

When you ask "What number is halfway between 15 and 545?" 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=545.

Halfway Between Line

To find the number halfway between 15 and 545, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 15 and 545 into our formula, we get:

(15 + 545)/2 = 280

Thus, the number halfway between 15 and 545 is 280.

To check that our answer is correct, we subtract 15 from 280 and subtract 280 from 545 and compare the two numbers:

280 - 15 = 265
545 - 280 = 265

As you can see, the halfway number is 265 higher than 15 and 265 lower than 545. Therefore, our halfway between answer of 280 above is correct.
