WebOct 18, 2024 · If ρ > 1 or ρ = ∞, then ∞ ∑ n = 1an diverges. If ρ = 1, the test does not provide any information. Proof Let ∞ ∑ n = 1an be a series with nonzero terms. We begin with the proof of part i. In this case, ρ = limn → ∞ ∣ an + 1 an ∣ < 1. Since 0 ≤ ρ < 1, there exists R such that 0 ≤ ρ < R < 1. Let ε = R − ρ > 0.

A lower bound which actually belongs to the set is called a minimum. Fortunately, once we have the LUB Axiom, we do not need an-other axiom to guarantee the existence of inf’s.
