Halfway Between 7 and 287

When you ask "What number is halfway between 7 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=7 and Y=287.

Halfway Between Line

To find the number halfway between 7 and 287, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 7 and 287 into our formula, we get:

(7 + 287)/2 = 147

Thus, the number halfway between 7 and 287 is 147.

To check that our answer is correct, we subtract 7 from 147 and subtract 147 from 287 and compare the two numbers:

147 - 7 = 140
287 - 147 = 140

As you can see, the halfway number is 140 higher than 7 and 140 lower than 287. Therefore, our halfway between answer of 147 above is correct.
