DO 4. (3pts) Can we conclude whether the series > an converges or not by using the Direct n= 1 Comparison Test with ) on? Explain why. n=1 7n an I br 4 + 1 An n= 1 n=1 n= 1 5. (4pts) Determine whether the following series is convergent or divergent. If you use either the Direct Comparison Test or Limit Comparison Test, state clearly why your choice of bn is convergent or divergent. n= 1 Do 3n2 + 2n + 3 no - n +5
