**1).**The series is: × 1 – 2, × 2 – 3, × 3 – 4, × 4 – 5, ….

**Answer: a)**

**2).**The series is: (13)

^{3}, (15)

^{3}, (17)

^{3}, (19)

^{3}, …

**Answer: d)**

**3).**The series is:

27 + 32 = 59; 32 + 59 = 91; 59 + 91 = 150;

91 + 150 = 241; 150 + 241 = 391

**Answer: e)**

**4).**The series is: +2, +2, +3, +3, +4, +4, …

**Answer: d)**

**5).**The series is a combination of two

Series:

Series I: 15 + 4 = 19; 19 + 4 = 23; 23 + 4 = 27

Series II: 16 + 2 = 18; 18 + 2 = 20; 20 + 2 = 22

**Answer: a)**

**6).**The series is 9

^{3}, 11

^{3}, 13

^{3}, 15

^{3}, 17

^{3}, …
