Practical Examples of Series Convergence and Divergence

Example 1: Geometric Series

Suppose we have:

  • Common ratio (r) = 0.5

Result:

  • Status: Convergent
  • Conclusion: Since |r| < 1, the series converges

Explanation:
In geometric series, convergence depends entirely on the absolute value of the ratio. If it is less than 1, the infinite sum approaches a finite value.


Example 2: p-Series

Suppose:

  • p = 2

Result:

  • Status: Convergent
  • Conclusion: Since p > 1, the series converges

Explanation:
A p-series converges only when the exponent p is greater than 1. Otherwise, it diverges.


Example 3: nth-Term Test

Suppose:

  • Limit of aₙ = 3

Result:

  • Status: Divergent
  • Conclusion: Since limit ≠ 0, the series diverges

Explanation:
If the limit of the nth term is not zero, the series cannot converge.
