Halfway Between 88 and 690

When you ask "What number is halfway between 88 and 690?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=88 and Y=690.

Halfway Between Line

To find the number halfway between 88 and 690, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 88 and 690 into our formula, we get:

(88 + 690)/2 = 389

Thus, the number halfway between 88 and 690 is 389.

To check that our answer is correct, we subtract 88 from 389 and subtract 389 from 690 and compare the two numbers:

389 - 88 = 301
690 - 389 = 301

As you can see, the halfway number is 301 higher than 88 and 301 lower than 690. Therefore, our halfway between answer of 389 above is correct.
