When you ask "What number is halfway between 81 and 749?" 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=749.
To find the number halfway between 81 and 749, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 81 and 749 into our formula, we get:
(81 + 749)/2 = 415
Thus, the number halfway between 81 and 749 is 415.
To check that our answer is correct, we subtract 81 from 415 and subtract 415 from 749 and compare the two numbers:
415 - 81 = 334
749 - 415 = 334
As you can see, the halfway number is 334 higher than 81 and 334 lower than 749. Therefore, our halfway between answer of 415 above is correct.
