20 Points Which of the following statements is always true? (4 points) If an goes to 0 as n goes to infinity, then the summation of a sub n converges.
If 0 < an < 1, then the sequence {an} converges.
If the summation of a sub n and the summation of b sub n diverge, then the summation of the quantity of a sub n minus b sub n converges.
If 0 ≤ an ≤ bn and the summation of b sub n converges, then the summation of a sub n converges.
