Halfway Between 38 and 690

When you ask "What number is halfway between 38 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=38 and Y=690.

Halfway Between Line

To find the number halfway between 38 and 690, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 38 and 690 into our formula, we get:

(38 + 690)/2 = 364

Thus, the number halfway between 38 and 690 is 364.

To check that our answer is correct, we subtract 38 from 364 and subtract 364 from 690 and compare the two numbers:

364 - 38 = 326
690 - 364 = 326

As you can see, the halfway number is 326 higher than 38 and 326 lower than 690. Therefore, our halfway between answer of 364 above is correct.
