Determine whether the sequence converges or diverges. If it converges, find the limit. (If the sequence diverges, enter DIVERGES.) $a_n = 8\left(-\frac{7}{8}\right)^n$
Added by Sharon W.
Step 1
This is a geometric sequence with the first term $a = 8$ and the common ratio $r = -\frac{7}{8}$. Since $|r| = \left|-\frac{7}{8}\right| = \frac{7}{8} < 1$, the sequence converges. Show more…
