11. (2) here we have two alternate series , 28, 31 , 34 , and the other is 33, 36 , 39, so the next term would be 39.

12. (3)


13. (3) 3 ×3^2+1 = 28 , 4 ×4^2+1 = 65 , 5 ×5^2+1=126, 6 ×6^2+1=217  

14. (1) the sequence of the series is x 3, + 4 , x 5 , + 6 , x 7, last term will be 1127 + 8 = 1135.

15. (5) the series is x 2 + 1 , x 2 + 2 , x 2 + 3 , x 2 + 4. So the ? = 32 x 2 + 3 = 67
