Halfway Between 25 and 287

When you ask "What number is halfway between 25 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=25 and Y=287.

Halfway Between Line

To find the number halfway between 25 and 287, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 25 and 287 into our formula, we get:

(25 + 287)/2 = 156

Thus, the number halfway between 25 and 287 is 156.

To check that our answer is correct, we subtract 25 from 156 and subtract 156 from 287 and compare the two numbers:

156 - 25 = 131
287 - 156 = 131

As you can see, the halfway number is 131 higher than 25 and 131 lower than 287. Therefore, our halfway between answer of 156 above is correct.
