When you ask "What number is halfway between 21 and 274?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=21 and Y=274.
To find the number halfway between 21 and 274, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 21 and 274 into our formula, we get:
(21 + 274)/2 = 147.5
Thus, the number halfway between 21 and 274 is 147.5.
To check that our answer is correct, we subtract 21 from 147.5 and subtract 147.5 from 274 and compare the two numbers:
147.5 - 21 = 126.5
274 - 147.5 = 126.5
As you can see, the halfway number is 126.5 higher than 21 and 126.5 lower than 274. Therefore, our halfway between answer of 147.5 above is correct.
