Halfway Between 78 and 440

When you ask "What number is halfway between 78 and 440?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=78 and Y=440.

Halfway Between Line

To find the number halfway between 78 and 440, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 78 and 440 into our formula, we get:

(78 + 440)/2 = 259

Thus, the number halfway between 78 and 440 is 259.

To check that our answer is correct, we subtract 78 from 259 and subtract 259 from 440 and compare the two numbers:

259 - 78 = 181
440 - 259 = 181

As you can see, the halfway number is 181 higher than 78 and 181 lower than 440. Therefore, our halfway between answer of 259 above is correct.
