Halfway Between 100 and 698

When you ask "What number is halfway between 100 and 698?" 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=698.

Halfway Between Line

To find the number halfway between 100 and 698, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 698 into our formula, we get:

(100 + 698)/2 = 399

Thus, the number halfway between 100 and 698 is 399.

To check that our answer is correct, we subtract 100 from 399 and subtract 399 from 698 and compare the two numbers:

399 - 100 = 299
698 - 399 = 299

As you can see, the halfway number is 299 higher than 100 and 299 lower than 698. Therefore, our halfway between answer of 399 above is correct.
