Halfway Between 78 and 266

When you ask "What number is halfway between 78 and 266?" 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=266.

Halfway Between Line

To find the number halfway between 78 and 266, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 78 and 266 into our formula, we get:

(78 + 266)/2 = 172

Thus, the number halfway between 78 and 266 is 172.

To check that our answer is correct, we subtract 78 from 172 and subtract 172 from 266 and compare the two numbers:

172 - 78 = 94
266 - 172 = 94

As you can see, the halfway number is 94 higher than 78 and 94 lower than 266. Therefore, our halfway between answer of 172 above is correct.
