When you ask "What number is halfway between 77 and 142?" 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=142.
To find the number halfway between 77 and 142, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 77 and 142 into our formula, we get:
(77 + 142)/2 = 109.5
Thus, the number halfway between 77 and 142 is 109.5.
To check that our answer is correct, we subtract 77 from 109.5 and subtract 109.5 from 142 and compare the two numbers:
109.5 - 77 = 32.5
142 - 109.5 = 32.5
As you can see, the halfway number is 32.5 higher than 77 and 32.5 lower than 142. Therefore, our halfway between answer of 109.5 above is correct.
