Hello,
I am trying to find if this sequence is converging or diverging:

Here is my work, but I highly doubt it because it is based on intuition:

Since the first limit diverges and the second limit is not equal to 0, then the sequence diverges.
Does anyone have a better, systematic way of dealing with this sequence and any other sign alternating sequence with (-1)^n
Thank you
