Answer

La serie diverge.

Solution

Para analizar la convergencia de la serie , podemos utilizar la prueba de la razón.
Consideremos el término general de la serie:
Ahora, calculemos el cociente de términos sucesivos:
Simplificando esto, tenemos:
Descomponiendo el primer término:
Sabemos que tiende a cuando tiende a infinito. Por lo tanto, para grandes :
Ahora, consideremos el segundo término:
Para grande, , así que:
Por lo tanto, el cociente se comporta como:
Ahora, al tomar el límite cuando :
Dado que el límite es infinito, por la prueba de la razón, la serie diverge.
Por lo tanto, la serie diverge.

Bonus Knowledge

To analyze the convergence of the series , we can apply the ratio test. We explore the behavior of the terms as approaches infinity.
Consider the -th term of the series:
Now, evaluate the ratio of successive terms:
This simplifies to:
We can simplify it further:
The logarithmic term can be approximated using for large :
which approaches .
Thus, we get that:
As , the ratio diverges since . Therefore, by the ratio test, the series diverges.
