When you ask "What number is halfway between 75 and 777?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=75 and Y=777.
To find the number halfway between 75 and 777, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 75 and 777 into our formula, we get:
(75 + 777)/2 = 426
Thus, the number halfway between 75 and 777 is 426.
To check that our answer is correct, we subtract 75 from 426 and subtract 426 from 777 and compare the two numbers:
426 - 75 = 351
777 - 426 = 351
As you can see, the halfway number is 351 higher than 75 and 351 lower than 777. Therefore, our halfway between answer of 426 above is correct.
