Halfway Between 55 and 287

When you ask "What number is halfway between 55 and 287?" 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=287.

Halfway Between Line

To find the number halfway between 55 and 287, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 55 and 287 into our formula, we get:

(55 + 287)/2 = 171

Thus, the number halfway between 55 and 287 is 171.

To check that our answer is correct, we subtract 55 from 171 and subtract 171 from 287 and compare the two numbers:

171 - 55 = 116
287 - 171 = 116

As you can see, the halfway number is 116 higher than 55 and 116 lower than 287. Therefore, our halfway between answer of 171 above is correct.
