Halfway Between 78 and 349

When you ask "What number is halfway between 78 and 349?" 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=349.

Halfway Between Line

To find the number halfway between 78 and 349, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 78 and 349 into our formula, we get:

(78 + 349)/2 = 213.5

Thus, the number halfway between 78 and 349 is 213.5.

To check that our answer is correct, we subtract 78 from 213.5 and subtract 213.5 from 349 and compare the two numbers:

213.5 - 78 = 135.5
349 - 213.5 = 135.5

As you can see, the halfway number is 135.5 higher than 78 and 135.5 lower than 349. Therefore, our halfway between answer of 213.5 above is correct.
