Ʃ ,n=1,∞, (2/n^2+n)
Does this series converge or diverge?
Im not sure how to start can i use the comparison test here?

Both convergent and divergent series have an infinite number of terms that get smaller and smaller, so that observation is of no value. For example, do you know the p seriesits 2/((n^2)+n)
and I'm thinking it converges because you are adding an infinite amount of numbers that are continually getting smaller and smaller
The first step in a comparison test is to decide by examining your series whether you think it probably converges or diverges. This is usually decided by previous experience with previously analyzed series such as a p series. The next step depends on your expectation of convergence or divergence.if p is greater than 1 the series converges
im not very good at the comparison test and how to find what to cop are it to
