WebLesson Worksheet: The 𝑛th Term Divergence Test. In this worksheet, we will practice applying the 𝑛th term test for divergence which states that a series diverges if the limit of its 𝑛th term does not approach zero. Q1: True or False: If 𝑎 → 0 as 𝑛 → ∞, then ∞ 𝑎 is convergent. A True. B False. WebExample 1. Determine whether the sequence 3, 7, 11, 15, 19, 23, 27 … diverges using the nth term test. Solution. First, it helps if we can identify if the sequence is something we’ve learned in the past. Checking the difference between two consecutive terms, we have the following: 7 – 3 = 4. 19 – 15 = 4.
