Halfway Between 100 and 700

When you ask "What number is halfway between 100 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=100 and Y=700.

Halfway Between Line

To find the number halfway between 100 and 700, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 700 into our formula, we get:

(100 + 700)/2 = 400

Thus, the number halfway between 100 and 700 is 400.

To check that our answer is correct, we subtract 100 from 400 and subtract 400 from 700 and compare the two numbers:

400 - 100 = 300
700 - 400 = 300

As you can see, the halfway number is 300 higher than 100 and 300 lower than 700. Therefore, our halfway between answer of 400 above is correct.
