Halfway Between 55 and 291

When you ask "What number is halfway between 55 and 291?" 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=291.

Halfway Between Line

To find the number halfway between 55 and 291, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 55 and 291 into our formula, we get:

(55 + 291)/2 = 173

Thus, the number halfway between 55 and 291 is 173.

To check that our answer is correct, we subtract 55 from 173 and subtract 173 from 291 and compare the two numbers:

173 - 55 = 118
291 - 173 = 118

As you can see, the halfway number is 118 higher than 55 and 118 lower than 291. Therefore, our halfway between answer of 173 above is correct.
