8-89.
1. Given an, write the first 3 terms of the sequence and then evaluate . Homework Help ✎

1. an = 6 · ()n−1

2. an = −2 · (1.1)n−11

$a_1=6\left(\frac{1}{3}\right)^{1-1}=6(1)=6$

$\lim_{x \rightarrow \infty}a_n=6\left(\frac{1}{3}\right)^\infty=0$

$a_1=-2(1.1)^{1-1}=-2$

$\lim_{x \rightarrow \infty}\textit{a}_n=-2(1.1)^\infty=-\infty$
