Halfway Between 78 and 191

When you ask "What number is halfway between 78 and 191?" 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=191.

Halfway Between Line

To find the number halfway between 78 and 191, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 78 and 191 into our formula, we get:

(78 + 191)/2 = 134.5

Thus, the number halfway between 78 and 191 is 134.5.

To check that our answer is correct, we subtract 78 from 134.5 and subtract 134.5 from 191 and compare the two numbers:

134.5 - 78 = 56.5
191 - 134.5 = 56.5

As you can see, the halfway number is 56.5 higher than 78 and 56.5 lower than 191. Therefore, our halfway between answer of 134.5 above is correct.
