Halfway Between 15 and 251

When you ask "What number is halfway between 15 and 251?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=15 and Y=251.

Halfway Between Line

To find the number halfway between 15 and 251, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 15 and 251 into our formula, we get:

(15 + 251)/2 = 133

Thus, the number halfway between 15 and 251 is 133.

To check that our answer is correct, we subtract 15 from 133 and subtract 133 from 251 and compare the two numbers:

133 - 15 = 118
251 - 133 = 118

As you can see, the halfway number is 118 higher than 15 and 118 lower than 251. Therefore, our halfway between answer of 133 above is correct.
