Halfway Between 67 and 209

When you ask "What number is halfway between 67 and 209?" 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=209.

Halfway Between Line

To find the number halfway between 67 and 209, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 67 and 209 into our formula, we get:

(67 + 209)/2 = 138

Thus, the number halfway between 67 and 209 is 138.

To check that our answer is correct, we subtract 67 from 138 and subtract 138 from 209 and compare the two numbers:

138 - 67 = 71
209 - 138 = 71

As you can see, the halfway number is 71 higher than 67 and 71 lower than 209. Therefore, our halfway between answer of 138 above is correct.
