When you ask "What number is halfway between 7 and 449?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=7 and Y=449.
To find the number halfway between 7 and 449, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 7 and 449 into our formula, we get:
(7 + 449)/2 = 228
Thus, the number halfway between 7 and 449 is 228.
To check that our answer is correct, we subtract 7 from 228 and subtract 228 from 449 and compare the two numbers:
228 - 7 = 221
449 - 228 = 221
As you can see, the halfway number is 221 higher than 7 and 221 lower than 449. Therefore, our halfway between answer of 228 above is correct.
