1. 4;

Hence, there should be 60 in place of 59

1. 1;

Hence, there should be 27 in place of 30.

1. 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.

1. 3;

The series is

Hence, there should be 380 in place of 385.

1. 2;

The series is

Hence, there should be 21 in place of 29.

1. 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

9.Ans: B

14.Ans: D .3

15.Ans: A . 6
