When you ask "What number is halfway between 90 and 221?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=90 and Y=221.
To find the number halfway between 90 and 221, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 90 and 221 into our formula, we get:
(90 + 221)/2 = 155.5
Thus, the number halfway between 90 and 221 is 155.5.
To check that our answer is correct, we subtract 90 from 155.5 and subtract 155.5 from 221 and compare the two numbers:
155.5 - 90 = 65.5
221 - 155.5 = 65.5
As you can see, the halfway number is 65.5 higher than 90 and 65.5 lower than 221. Therefore, our halfway between answer of 155.5 above is correct.
