Halfway Between 78 and 629

When you ask "What number is halfway between 78 and 629?" 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=629.

Halfway Between Line

To find the number halfway between 78 and 629, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 78 and 629 into our formula, we get:

(78 + 629)/2 = 353.5

Thus, the number halfway between 78 and 629 is 353.5.

To check that our answer is correct, we subtract 78 from 353.5 and subtract 353.5 from 629 and compare the two numbers:

353.5 - 78 = 275.5
629 - 353.5 = 275.5

As you can see, the halfway number is 275.5 higher than 78 and 275.5 lower than 629. Therefore, our halfway between answer of 353.5 above is correct.
