Halfway Between 67 and 690

When you ask "What number is halfway between 67 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=67 and Y=690.

Halfway Between Line

To find the number halfway between 67 and 690, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 67 and 690 into our formula, we get:

(67 + 690)/2 = 378.5

Thus, the number halfway between 67 and 690 is 378.5.

To check that our answer is correct, we subtract 67 from 378.5 and subtract 378.5 from 690 and compare the two numbers:

378.5 - 67 = 311.5
690 - 378.5 = 311.5

As you can see, the halfway number is 311.5 higher than 67 and 311.5 lower than 690. Therefore, our halfway between answer of 378.5 above is correct.
