When you ask "What number is halfway between 77 and 145?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=77 and Y=145.
To find the number halfway between 77 and 145, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 77 and 145 into our formula, we get:
(77 + 145)/2 = 111
Thus, the number halfway between 77 and 145 is 111.
To check that our answer is correct, we subtract 77 from 111 and subtract 111 from 145 and compare the two numbers:
111 - 77 = 34
145 - 111 = 34
As you can see, the halfway number is 34 higher than 77 and 34 lower than 145. Therefore, our halfway between answer of 111 above is correct.
