Halfway Between 67 and 686

When you ask "What number is halfway between 67 and 686?" 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=686.

Halfway Between Line

To find the number halfway between 67 and 686, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 67 and 686 into our formula, we get:

(67 + 686)/2 = 376.5

Thus, the number halfway between 67 and 686 is 376.5.

To check that our answer is correct, we subtract 67 from 376.5 and subtract 376.5 from 686 and compare the two numbers:

376.5 - 67 = 309.5
686 - 376.5 = 309.5

As you can see, the halfway number is 309.5 higher than 67 and 309.5 lower than 686. Therefore, our halfway between answer of 376.5 above is correct.
