When you ask "What number is halfway between 81 and 516?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=81 and Y=516.
To find the number halfway between 81 and 516, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 81 and 516 into our formula, we get:
(81 + 516)/2 = 298.5
Thus, the number halfway between 81 and 516 is 298.5.
To check that our answer is correct, we subtract 81 from 298.5 and subtract 298.5 from 516 and compare the two numbers:
298.5 - 81 = 217.5
516 - 298.5 = 217.5
As you can see, the halfway number is 217.5 higher than 81 and 217.5 lower than 516. Therefore, our halfway between answer of 298.5 above is correct.
