Halfway Between 23 and 287

When you ask "What number is halfway between 23 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=23 and Y=287.

Halfway Between Line

To find the number halfway between 23 and 287, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 23 and 287 into our formula, we get:

(23 + 287)/2 = 155

Thus, the number halfway between 23 and 287 is 155.

To check that our answer is correct, we subtract 23 from 155 and subtract 155 from 287 and compare the two numbers:

155 - 23 = 132
287 - 155 = 132

As you can see, the halfway number is 132 higher than 23 and 132 lower than 287. Therefore, our halfway between answer of 155 above is correct.
