Halfway Between 15 and 487

When you ask "What number is halfway between 15 and 487?" 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=487.

Halfway Between Line

To find the number halfway between 15 and 487, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 15 and 487 into our formula, we get:

(15 + 487)/2 = 251

Thus, the number halfway between 15 and 487 is 251.

To check that our answer is correct, we subtract 15 from 251 and subtract 251 from 487 and compare the two numbers:

251 - 15 = 236
487 - 251 = 236

As you can see, the halfway number is 236 higher than 15 and 236 lower than 487. Therefore, our halfway between answer of 251 above is correct.
