Halfway Between 55 and 209

When you ask "What number is halfway between 55 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=55 and Y=209.

Halfway Between Line

To find the number halfway between 55 and 209, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 55 and 209 into our formula, we get:

(55 + 209)/2 = 132

Thus, the number halfway between 55 and 209 is 132.

To check that our answer is correct, we subtract 55 from 132 and subtract 132 from 209 and compare the two numbers:

132 - 55 = 77
209 - 132 = 77

As you can see, the halfway number is 77 higher than 55 and 77 lower than 209. Therefore, our halfway between answer of 132 above is correct.
