A conceptual representation displaying two sequences. The first sequence shows a set of geometrically shaped boxes each consisting a number starting from 1 and being multiplied by 3 each time to form an arithmetic progression, representing a possible recursive sequence. The second sequence shows a similar set of boxes, each containing a number starting from 2 and being added by 3 each time to form a non-recursive sequence. The third sequence is depicted as a separate non-recursive sequence where the pattern is not clear between the numbers 2, 4, 6, and 10.

Which of the following is an example of a recursive sequence?

1, 3, 9, 27, ...
2, 5, 8, 11, ...
2, 4, 6, 10, ...

1, 3, 9, 27, ...
