WebFeb 14, 2024 · Im trying to find the nth term for this sequence but since it is not linear or geometric I'm not sure how to. I worked out that the recursive formula is: \begin{gather} a_1 = 1 \\ a_{n + 1} = 10a_{n} + 6 \end{gather} I'm trying to write this as an nth term and I saw that one solution was: \begin{gather} \frac{1}{6}\left ( 10 ^{n}-4\right ) \end ... WebMy recommended process for dealing with series is: (1) If the series is alternating, then compute the limit of the terms. If the limit is 0 , then the alternating series test applies; take the absolute values of the terms and proceed below with a series of positive terms. If the limit is not zero, then by the nth term test, 1 the series diverges.
