If you don't know the limit comparison test or the integral test, you need to learn them. (For these problems, surely you know the "standard" tests.)

Oh, mate thank you so much. I know all of them but just had no practice before, so I just didn't notice this(silly me). I tried d'Alembert's ratio test, and Raabe's test but things didn't work out) So thank u one more time
