When you ask "What number is halfway between 79 and 619?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=79 and Y=619.

To find the number halfway between 79 and 619, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 79 and 619 into our formula, we get:
(79 + 619)/2 = 349
Thus, the number halfway between 79 and 619 is 349.
To check that our answer is correct, we subtract 79 from 349 and subtract 349 from 619 and compare the two numbers:
349 - 79 = 270
619 - 349 = 270
As you can see, the halfway number is 270 higher than 79 and 270 lower than 619. Therefore, our halfway between answer of 349 above is correct.
