#### Number Series Questions for Bank Exams

#1. In the following number series, a wrong number is given. Find out the wrong number.

781, 783, 793, 791, 805, 800

#1. 783

#2.793

#3.791

#4. 805

#5. 800

Solution: Correct Answer is option 5.

Explanation:

The given series follows the pattern

⇒ 156 × 5 + 1 = 781

⇒ 157 × 5 – 2 = 783

⇒ 158 × 5 + 3 = 793

⇒ 159 × 5 – 4 = 791

⇒ 160 × 5 + 5 = 805

⇒ 161 × 5 – 6 = 799

Therefore, the wrong number in the given series is 800.

#2. 6, 12, 48, 264, 1560?

#1. 9636

#2. 9864

#3. 9432

#4. 9336

#5. 9268

Solution: Correct answer is option 4

Explanation:

 Series Pattern Given Series 6 6 6 + 61 = 12 12 12 + 62 = 48 48 48 + 63 = 264 264 264 + 64 = 1560 1560 1560 + 65 = 9336 9336

Hence, 9336 is correct.

#3. Directions: A number series is given in the following question. The first element of a new series is also given followed by (a), (b), (c), etc. Determine the unknown element in the new series based upon the pattern followed by the given series.

8, 23, 90, 447, 2678

5, (a), (b), (c), (d), (e)

What will come in place of (d)?

#1. 1848

#2. 1598

#3. 2126

#4. 1967

#5. 2286

Solution: Correct option is 2

Clearly, the elements are multiplied by integers starting from 3 and then subtracted by integers starting from 1.

⇒ 23 = 8 × 3 – 1

⇒ 90 = 23 × 4 – 2

⇒ 447 = 90 × 5 – 3

⇒ 2678 = 447 × 6 – 4 and so on.

⇒ (a) = 5 × 3 – 1 = 14

⇒ (b) = 14 × 4 – 2 = 54

⇒ (c) = 54 × 5 – 3 = 267

⇒ (d) = 267 × 6 – 4 = 1598

Therefore, (d) = 1598

#4. What will come in place of question mark (?) in the following number series?

70, 105, 157.5, 236.25, ?

#1. 325.755

#2. 555.255

#3. 405.255

#4. 354.375

#5. 345.675

Solution: Correct Option is 4

Explanation:

The pattern for the given series:

⇒ 70 × 1.5 = 105

⇒ 105 × 1.5 = 157.5

⇒ 157.5 × 1.5 = 236.25

⇒ 236.25 × 1.5 = 354.37 = ?

Therefore, the answer to? = 354.375

#5. Find out the wrong term in the following number series.

3, 3, 4.5, 9, 22.5, 67.5, 270

#1. 9

#2. 270

#3. 22.5

#4. 3

#5. None of these

Solution: Correct Option is 2

The series follows the following pattern:

3

3 = 3 × 1

4.5 = 3 × 1.5

9 = 4.5 × 2

22.5= 9 × 2.5

67.5 = 22.5 × 3

270 ≠ 67.5 × 3.5

Therefore, 270 is the wrong number in the series.

#### Number Series Questions for Bank Exams

#1. What should come in place of the question mark ‘?’ in the following number series?

799, 803, 830, 846,?

#1. 896

#2. 923

#3. 971

#4. 864

#5. 917

Solution: Correct Option is 3

The pattern for the given series:

⇒ 799 + 22 = 799 + 4 = 803

⇒ 803 + 33 = 803 + 27 = 830

⇒ 830 + 42 = 830 + 16 = 846

⇒ 846 + 53 = 846 + 125 = 971 = ?

Hence, 971 is the right answer.

#2. In the following number series, only one number is wrong. Find out the wrong number.

1   8   22   45   71   106   148

#1. 8

#2. 71

#3. 45

#4. 106

#5. 148

Solution: Right option is 3

The given series is in the following pattern:

1

1 + 7 = 8

8 + 14 = 22

22 + 21 = 43 ≠ 45

43 + 28 = 71

71 + 35 = 106

106 + 42 = 148

So, the wrong number is 45.

#3. Directions: A number series is given in the following question. The first element of a new series is also given followed by (a), (b), (c), etc. Determine the unknown element in the new series based upon the pattern followed by the given series.

4, 5, 13, 44, 183, 924

8, (a), (b), (c), (d), (e)

What will come in place of (c)?

#1. 61

#2. 73

#3. 68

#4. 65

#5. 74

Solution: Correct Option is 3

Clearly, the elements are multiplied by integers starting from 1 and then odd numbers are added in succession.

⇒ 5 = 4 × 1 + 1

⇒ 13 = 5 × 2 + 3

⇒ 44 = 13 × 3 + 5

⇒ 183 = 44 × 4 + 7

⇒ 924 = 183 × 5 + 9

Therefore, (a) = 8 × 1 + 1 = 9

⇒ (b) = 9 × 2 + 3 = 21

⇒ (c) = 21 × 3 + 5 = 68

So, (c) = 68

#4. Find out the wrong number in the series: 17, 23, 35, 55, 85, 125

#1. 17

#2. 23

#3. 55

#4. 85

#5. 125

Solution: Correct Answer is option 5

Explanation:

⇒ 17 + 2 × 3 = 23

⇒ 23 + 3 × 4 = 35

⇒ 35 + 4 × 5 = 55

⇒ 55 + 5 × 6 = 85

⇒ 85 + 6 × 7 = 127

Therefore, the wrong number in the series is 125

#5. What should come in place of the question mark ‘?’ in the following number series?

40, 90, 170, 350, ?

#1. 700

#2. 690

#3. 500

#5. 400

#6. 645

Solution: Correct option is 2.

Explanation:

The series follows the following pattern:

⇒ 40 × 2 + 10 = 90

⇒ 90 × 2 – 10 = 170

⇒ 170 × 2 + 10 = 350

⇒ 350 × 2 – 10 = 690

Therefore, the value of? is 690.
