Quizplus · Accepted Answer

The first term of the sequence is given by the coefficient before the TBX number, which is -2 in this case. The recursion formula suggests that each term is obtained by multiplying the previous term by -2 and adding 3 to it. So, the first five terms of the sequence are: -2, -5, -11, -23, -47. Therefore, the best choice is E.
