135, 405, 1215.
Each term is three times the previous (15 = 5*3, 45 = 15*3).
The first term after 45 is 45*3 = 135.
The next term is 135*3 = 405
The third term after 45 is 405*3 = 1215.

Take each term and multiply it by 3 to get the next term in the sequence.

The patters
5 x 3 = 15
15 x 3 = 45
45 = x = 135
135 = 3 = 405
405 x 3 = 1215
