3  10  33  111  349  1072  3252

Correct Answer: (1) 33
Solution:The pattern is :

3 3 + 1² = 9 + 1 = 10

10 3 + 2² = 30 + 4

= 34 ≠ 33

= 34 3 +  = 102 + 9 = 111

111 3 +  = 333 + 16 = 349

349 3 +  = 1047 + 25

= 1072

2  6  24  96  285  568  567

Correct Answer: (3) 24
Solution:The pattern is :

2 6 - 6 = 6

6 5 - 5 = 25 ≠ 24

25 4 - 4 = 96

96 3 - 3 = 285

39. In the following number series, a wrong number is given. Identify the wrong number that does not follow the given pattern.
