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.
