Use the Comparison Test to Determine Whether the Infinite Series $\sum _ { k = 1 } ^ { \infty } \frac { 1 } { k ^ { 3 } + k - 1 }$

Short Answer

Use the comparison test to determine whether the infinite series $\sum _ { k = 1 } ^ { \infty } \frac { 1 } { k ^ { 3 } + k - 1 }$ is convergent or divergent.
Enter just "convergent" or "divergent".
