Well, somehow I feel this series is incomplete or has a missing term..
because the series can be analysed this way -
2, 2*3 -1, 5*3 - 1, ?? , 41*3 - 1, 122*3-1, ..
Now, I feel at the place where I put "??" there should be a 41 for the series to be complete. Thats what I feel, because then the series follows a general rule and then the answer would be b) 1094.
