Series Sudoku (Fun With Sudoku #18)

This puzzle I created this for the 21st Indian Sudoku Mock Test and now re-posting it again as the 18th Sudoku in Fun With Sudoku League. Can you solve this Series Sudoku puzzle?

This is my third Sudoku for Series Sudoku type. I have earlier posted this Sudoku Type with the title Series Sudoku (Fun With Sudoku #9) and Series Sudoku (Fun With Sudoku #15). I have also written about the story behind the given series in my first post of Series Sudoku titled Sudoku (Fun With Sudoku #9).

The Series in this Sudoku looks interesting and frankly, as of now even I am not able to recall the logic of this series. I think I should start putting the answers to these Series before I forget all of them. Anyway, the moment I remember the logic of this series, I will post it as the answer to this series. Meanwhile, if you can come up with any logic for this series, please do comment about it.
