Halfway Between 28 and 690

When you ask "What number is halfway between 28 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=28 and Y=690.

Halfway Between Line

To find the number halfway between 28 and 690, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 28 and 690 into our formula, we get:

(28 + 690)/2 = 359

Thus, the number halfway between 28 and 690 is 359.

To check that our answer is correct, we subtract 28 from 359 and subtract 359 from 690 and compare the two numbers:

359 - 28 = 331
690 - 359 = 331

As you can see, the halfway number is 331 higher than 28 and 331 lower than 690. Therefore, our halfway between answer of 359 above is correct.
