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
