Halfway Between 78 and 516

When you ask "What number is halfway between 78 and 516?" 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=516.

Halfway Between Line

To find the number halfway between 78 and 516, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 78 and 516 into our formula, we get:

(78 + 516)/2 = 297

Thus, the number halfway between 78 and 516 is 297.

To check that our answer is correct, we subtract 78 from 297 and subtract 297 from 516 and compare the two numbers:

297 - 78 = 219
516 - 297 = 219

As you can see, the halfway number is 219 higher than 78 and 219 lower than 516. Therefore, our halfway between answer of 297 above is correct.
