Solutions for Sequence and Series Questions for SBI Clerk:

Solutions: 

1) Answer (B)
The difference between consecutive terms of the series is doubling as given below.
For example, 16-12 = 4
24-16 = 8
40-24 = 16
So, the number to come next is 40+32 = 72

2) Answer (C)
Each term of the number series is one more than double the previous number.
For example, 19 = 2*9 + 1
39 = 2*19 + 1
79 = 2*39 + 1
So, the number to come next is 2*79 + 1 = 159

3) Answer (D)
The difference between consecutive terms of the number series are squares of odd natural
numbers.
For example, 17-8 = 9
42-17 = 25
91-42 = 49
Hence, the number to come next is 91+81 = 172

4) Answer (E)
The number series given above follows the pattern described below.
For example, 8 = 7*1 + 1
18 = 8*2 + 2
57 = 18*3 + 3
So, the number to come next is 57*4 + 4 = 232. As this is not given in the options given, the answer is option (e)

5) Answer (E)
Each number in the given series is one fourth the previous number.
For example, 960 = 3840/4
240 = 960/4
60 = 240/4
So, the number to come next is 60/4 = 15

6) Answer (D)
The numbers given in the series follow the pattern described below
6 = 4*1 + 2
16 = 6*2 + 4
54 = 16*3 + 6
Hence, the number to come next will be 54*4 + 8 = 224

7) Answer (C)
Each term in the series follows the pattern given below.
39 = 5*8 – 1
272 = 39*7 – 1
1631 = 272*6 – 1
Hence, the next term in the series will be 1631*5 – 1 = 8154

8) Answer (B)
Each term in the series is equal to the previous number divided by 4.
For example, 768 = 192*4
192 = 48*4
48 = 12*4
Hence, the next number in the series will be 12/4 = 3

9) Answer (E)
The difference between consecutive terms of the series are perfect squares of even natural
numbers.
For example, 16 – 12 = 4
32 – 16 = 16
68 – 32 = 36
Hence, the next number will be 68 + 64 = 132

10) Answer (A)
The series given above follows the pattern given
15 = 2*7 + 1
32 = 15*2 + 2
67 = 32*2 + 3
138 = 67*2 + 4
Hence, the required answer is 138

We hope that you have gone through the sequence and series questions and answers of SBI clerk.
