Halfway Between 15 and 700

When you ask "What number is halfway between 15 and 700?" 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=700.

Halfway Between Line

To find the number halfway between 15 and 700, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 15 and 700 into our formula, we get:

(15 + 700)/2 = 357.5

Thus, the number halfway between 15 and 700 is 357.5.

To check that our answer is correct, we subtract 15 from 357.5 and subtract 357.5 from 700 and compare the two numbers:

357.5 - 15 = 342.5
700 - 357.5 = 342.5

As you can see, the halfway number is 342.5 higher than 15 and 342.5 lower than 700. Therefore, our halfway between answer of 357.5 above is correct.
