Determine whether the following sequence converges or diverges. an = {2arctan(n) n + 7} If the sequence is convergent, state the limit of the sequence. If the sequence is convergent, state the limit of the sequence. In the case of a convergent sequence, write your answer as an integer or a reduced fraction. If the solution involves a square root of a number, type sqrt in front of the number. For example, if the solution involves 2 , then type sqrt(2) for the corresponding part of the solution. If the sequence is divergent, type DIV.
