An Abundant number who's proper factors (all factors EXCEPT ITSELF) added are greater than the number. IE 12 (1+2+3+4+6=15, 15>12).
Therefore, this is like asking to list all numbers. It is simply not possible. There is literally no end to them. However, here are quite a few:
12, 18, 20, 24, 30, 36, 40, 42, 48, 54, 56, 60, 66, 70, 72, 78, 80, 84, 88, 90, 96, 100, 102

An abundant number is any natural number (starting from 1) that is less than the sum of all its divisors excepting itself (the set of "all its divisors excepting itself" is also known as the set of its "proper divisors"). The lowest abundant number is twelve, and the first nine (all of those between one and fourty-nine, inclusive) are: 12 18 20 24 30 36 40 42 48
There are no Thabit numbers at all on the list you've provided.
First, you add them all up. Then you divide what you've got by how much numbers you've got in the list.
1,2,3,4,5,7,8,9,10,11,13,14,15,16,17,19,21,21,23,25,26,27,29,31,32,33,34,35,37,38,39,41,43,44,45,46,47,49,50,51,52,53,55,57,58,59,61
That's an infinite list, too long to write here. Perhaps you could specify a range.
Yes, this is well known. All integral multiples of any perfect, or abundant number must be an abundant number.

No. All prime numbers are deficient.
no, 945 is the first abundant odd number though
No, all prime numbers are deficient.
It would be impossible to list all the even numbers.
That's an infinite list.
That's an infinite list.
It is impossible to list the infinite number of prime numbers and composite numbers.
False. The least common multiple (LCM) of a list of numbers is the smallest number that is divisible by each number in the list, not just a multiple. In other words, the LCM is the smallest number that is a common multiple of all the numbers in the list.
