Integers are positive and negative whole numbers. Integers between -5 and 3 are -4, -3, -2, -1, 0, 1, 2
Answer:
II and II only.
Step-by-step explanation:
The first series converges because the common ratio r is 0.8 (<1).
II diverges as |r| > 1.
III is an alternating series with r = -4 - that is |r| = 4 so it diverges.
