Some questions of abundance (Posted on 2015-10-28) Difficulty: 2 of 5
Under what conditions is the number 2n*p an abundant number? Where n is a positive integer and p is prime.

How about 3n*p?

How about 2*pn?

Recall an abundant number is one whose proper factors sum to more than the number. For example 18 is abundant because 1+2+3+6+9 > 18.
