Halfway Between 78 and 340

When you ask "What number is halfway between 78 and 340?" 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=340.

Halfway Between Line

To find the number halfway between 78 and 340, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 78 and 340 into our formula, we get:

(78 + 340)/2 = 209

Thus, the number halfway between 78 and 340 is 209.

To check that our answer is correct, we subtract 78 from 209 and subtract 209 from 340 and compare the two numbers:

209 - 78 = 131
340 - 209 = 131

As you can see, the halfway number is 131 higher than 78 and 131 lower than 340. Therefore, our halfway between answer of 209 above is correct.
