Answer:
convergent
Step-by-step explanation:
the function increases or decreases or as the number of terms of the series increases.
Divergent
The series can be written as:
∑ 1 / (4n − 1)
We can compare this to 1 / (5n). 1 / (5n) is smaller and diverges (p-series test). Therefore, the larger function also diverges.
