In a geometric series each term is obtained by multiplying the previous term by a specific number. In other words, we can say that the ratio of two consecutive terms of the geometric sequence is the same. From the given options, option D satisfies these conditions.
First term is 2. Second term is obtained by multiplying 2 with 2 which equals 4. Third term is obtained by multiplying previous term (4) by 2 and so on..
Therefore, the correct answer is option D: 2, 4, 8, 16, 32
