Halfway Between 55 and 188

When you ask "What number is halfway between 55 and 188?" 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=188.

Halfway Between Line

To find the number halfway between 55 and 188, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 55 and 188 into our formula, we get:

(55 + 188)/2 = 121.5

Thus, the number halfway between 55 and 188 is 121.5.

To check that our answer is correct, we subtract 55 from 121.5 and subtract 121.5 from 188 and compare the two numbers:

121.5 - 55 = 66.5
188 - 121.5 = 66.5

As you can see, the halfway number is 66.5 higher than 55 and 66.5 lower than 188. Therefore, our halfway between answer of 121.5 above is correct.
