Halfway Between 15 and 900

When you ask "What number is halfway between 15 and 900?" 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=900.

Halfway Between Line

To find the number halfway between 15 and 900, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 15 and 900 into our formula, we get:

(15 + 900)/2 = 457.5

Thus, the number halfway between 15 and 900 is 457.5.

To check that our answer is correct, we subtract 15 from 457.5 and subtract 457.5 from 900 and compare the two numbers:

457.5 - 15 = 442.5
900 - 457.5 = 442.5

As you can see, the halfway number is 442.5 higher than 15 and 442.5 lower than 900. Therefore, our halfway between answer of 457.5 above is correct.
