Halfway Between 15 and 535

When you ask "What number is halfway between 15 and 535?" 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=535.

Halfway Between Line

To find the number halfway between 15 and 535, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 15 and 535 into our formula, we get:

(15 + 535)/2 = 275

Thus, the number halfway between 15 and 535 is 275.

To check that our answer is correct, we subtract 15 from 275 and subtract 275 from 535 and compare the two numbers:

275 - 15 = 260
535 - 275 = 260

As you can see, the halfway number is 260 higher than 15 and 260 lower than 535. Therefore, our halfway between answer of 275 above is correct.
