E. 7

**ANSWERS :–**

**4;**

Hence, there should be 60 in place of 59

**1;**

Hence, there should be 27 in place of 30.

**5;**

The series is

2³ – 3 = 5, 3³ – 4 = 23, 4³-5 = 59

5³-6 = 119, 6³ – 7 = 209, 7³ – 8 = 335

Hence, there should be 23 in place of 30.

**3;**

The series is

Hence, there should be 380 in place of 385.

**2;**

The series is

Hence, there should be 21 in place of 29.

- 5 ✕ 1-1=4

4 ✕ 2-1=7

7 ✕ 3-1=20

20 ✕ 4-1=79

79 ✕ 5-1=394

**Ans 394**

**7.**18 ✕ 0.5 = 9

⇒ 9 ✕ 1 = 9

⇒ 9 ✕ 1.5 = 13.5

⇒ 15.5 ✕ 2= 27

⇒ 27 ✕ **2.5 = 67.5 answers**

**8.There is pattern between the differences of the numbers given in the series.**

83 – 3 = 80

152 – 83 = 69

209 – 152 = 57

253 -209 = 44

Now

⇒ 80 – 69 = -11

⇒ 69 – 57 = -12

⇒ 57 – 44 = -13

⇒ 44 – **30** = -14

**30 is the answers**
