Halfway Between 67 and 911

When you ask "What number is halfway between 67 and 911?" 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=911.

Halfway Between Line

To find the number halfway between 67 and 911, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 67 and 911 into our formula, we get:

(67 + 911)/2 = 489

Thus, the number halfway between 67 and 911 is 489.

To check that our answer is correct, we subtract 67 from 489 and subtract 489 from 911 and compare the two numbers:

489 - 67 = 422
911 - 489 = 422

As you can see, the halfway number is 422 higher than 67 and 422 lower than 911. Therefore, our halfway between answer of 489 above is correct.
