Halfway Between 10 and 690

When you ask "What number is halfway between 10 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=10 and Y=690.

Halfway Between Line

To find the number halfway between 10 and 690, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 10 and 690 into our formula, we get:

(10 + 690)/2 = 350

Thus, the number halfway between 10 and 690 is 350.

To check that our answer is correct, we subtract 10 from 350 and subtract 350 from 690 and compare the two numbers:

350 - 10 = 340
690 - 350 = 340

As you can see, the halfway number is 340 higher than 10 and 340 lower than 690. Therefore, our halfway between answer of 350 above is correct.
