is it converges absolutly ,or with condition(dont know the english term), or is it diverges? from nth root method of cauchy the limit of (2k+3)(3k-4) is infinity ??

no they have different powers numerator will be 1 denominator is -1
I did not say anything about your series. I've just answered the question which you edited it. In order to test the series for absolutely/condintionally convergent, you should check the absolute series. Did try anything for ?
first we need to test the absolute value series the n'th root doesnt work because i get a limit of infinity what you did what takng the expression witout the powers on numerator and denominator
