Adding together and finding the mean multiple times, I noticed that whatever even number I chose, the first number(in this case one) and the last number ( in this case n), when you wipe that number out. The mean of all the other numbers is ALWAYS a whole number. Additionally, for example, if n=6, the mean if 1 was wiped out is 4. The mean if 6 was wiped out is 3.
