Halfway Between 9 and 259

When you ask "What number is halfway between 9 and 259?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=9 and Y=259.

Halfway Between Line

To find the number halfway between 9 and 259, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 9 and 259 into our formula, we get:

(9 + 259)/2 = 134

Thus, the number halfway between 9 and 259 is 134.

To check that our answer is correct, we subtract 9 from 134 and subtract 134 from 259 and compare the two numbers:

134 - 9 = 125
259 - 134 = 125

As you can see, the halfway number is 125 higher than 9 and 125 lower than 259. Therefore, our halfway between answer of 134 above is correct.
