When you ask "What number is halfway between 74 and 144?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=74 and Y=144.

To find the number halfway between 74 and 144, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 74 and 144 into our formula, we get:
(74 + 144)/2 = 109
Thus, the number halfway between 74 and 144 is 109.
To check that our answer is correct, we subtract 74 from 109 and subtract 109 from 144 and compare the two numbers:
109 - 74 = 35
144 - 109 = 35
As you can see, the halfway number is 35 higher than 74 and 35 lower than 144. Therefore, our halfway between answer of 109 above is correct.
