A number is abundant if the sum of its factors is greater than twice the number.
So in the range given there are 3 and they are:
12, 18 & 20 as:
12 has factors of 1,12,2,6,3,4 which total 28. 28 > (2 * 12)
18 has factors of 1,18,2,9,3,6 which total 39. 39 > (2 * 18)
20 has factors of 1,20,2,10,4,5 which total 42. 42 > (2 * 20)
12, 18, 20, 24, 30

There are 20 natural numbers between 32 and 53.
There are 20 odd numbers between 19 and 57
half of (50 - 20)
