Determining if a series is convergent or divergent is an important process for mathematicians and scientists. Convergence of a sequence refers to the property that its elements eventually approach a certain value (or infinity) as the index increases. Divergence, on the other hand, implies that the sequence has no limit, meaning it can never reach any specific value regardless of how much time passes. Therefore it is key to understand how to determine if a given series is convergent or divergent in order to properly study it and utilize its properties in various problems.

The first step in determining whether a series converges or not is by performing analysis using mathematical tests such as comparison test, integral test, root test etc. The comparison test involves comparing two existing sequences and checking whether their respective limits exist (if they do then one can conclude that both converge). Similarly for integral test one needs to check whether an existing integral’s definite value exists (which would indicate convergence). In case none of these tests yield conclusive result then there are multiple other methods available which need to be applied including ratio test, alternating series test etc.

## Steps to Determine if the series is convergent

Once all mathematical analysis have been performed and results summarized we will move on second step i.e., graphical representation of data points associated with each term in sequence along with limit line so one can easily compare them visually and verify if they occur later on regular intervals indicating more towards convergence rather than divergence else this could hint towards divergence behavior itself leading us either perform another mathematical method based upon nature of graph obtained or move onto third step straight away i.e., oscillation theorem which tells us whether our particular sequence falls into category regarding oscillation around some fixed point indicating presence of both positive & negative values alternately leading us again conclusion about convergence/divergence based upon interval size after successive terms when compared against previous ones recursively over entire range calculated till date through different methods used previously as well current results obtained from above theorem application too as depicted below:

Time-Step -> Sequence Term Value > Oscillation Intervals

0 10 5-7

1 12 3-5

2 14 1-3

. . .

N x -∞+ ∞

In last step we apply alternate formulae like Dirichlet’s Test & Abel’s Theorem which help identify exactly at what point does our particular cumulative partial sum tends towards single finite number thus concluding our whole exercise with definite conclusion about convergence/divergence depending upon whole set studied iteratively throughout this steps mentioned above thereby providing full proof understanding behind why something behaves same way under given conditions ensuring correctness even further while utilizing information gathered via same elsewhere wherever relevant making sure conclusions drawn here valid there too!
