A. 102
B. 121
C. 123
D. 117
Correct Answer: Option A
• The differences between consecutive terms increase by 4: 212 - 14 = 198 198 - 18 = 180 180 - 22 = 158 158 - 26 = 132 132 - 30 = 102 • Therefore, the next term is 102.
General Intelligence Number Series Number Series Q. #6547 (CAT-I)

A. 98
B. 96
C. 100
D. 94
Correct Answer: Option D
• The differences between consecutive terms decrease by 11 at each step: 325 - 66 = 259 259 - 55 = 204 204 - 44 = 160 160 - 33 = 127 127 - 22 = 105 105 - 11 = 94 • Thus, the next number is 94.
General Intelligence Number Series Number Series Q. #6546 (CAT-I)
Find the missing term in the sequence: 5, 16, 51, 158, ?
A. 483
B. 1454
C. 481
D. 1452
Correct Answer: Option C
• The pattern is multiplying by 3 and adding consecutive odd numbers: 5 × 3 + 1 = 16 16 × 3 + 3 = 51 51 × 3 + 5 = 158 158 × 3 + 7 = 474 + 7 = 481 • Hence, the correct term is 481.
General Intelligence Number Series Number Series Q. #6545 (CAT-I)
Find the missing number in the given series: 0, 5, 60, 615, ?
A. 6030

General Intelligence Number Series Number Series Q. #6544 (CAT-I)
Find the missing number in the following series: 2123, 3234, 4345, 5456, ?
A. 6567
B. 6467
C. 6556
D. 6566
Correct Answer: Option A
• The pattern follows an addition of 1111 to each successive term: 2123 + 1111 = 3234 3234 + 1111 = 4345 4345 + 1111 = 5456 5456 + 1111 = 6567 • Alternatively, looking at the individual digits of each term: 2-1-2-3, 3-2-3-4, 4-3-4-5, 5-4-5-6, the next set is 6-5-6-7, giving 6567.
General Intelligence Number Series Number Series Q. #6543 (CAT-I)
Find the odd/wrong number in the given number series: 28, 44, 68, 80, 92
A. 28
B. 44
C. 68
D. 80
Correct Answer: Option D
Each term is a multiple of 4 with a prime factor: 28 = 4 × 7 44 = 4 × 11 68 = 4 × 17 80 = 4 × 20 (20 is not a prime number) 92 = 4 × 23 • The numbers multiplied by 4 are consecutive primes (7, 11, 17, 19 would give 76, 23). Since 20 is composite, 80 is the wrong/inconsistent term.
General Intelligence Number Series Number Series Q. #6542 (CAT-I)
Find the wrong number in the given series: 216, 163, 120, 72, 24
A. 216
B. 163
C. 72
D. 24
Correct Answer: Option B
The pattern has a constant common difference of -48: 216 - 48 = 168 (given as 163) 168 - 48 = 120 120 - 48 = 72 72 - 48 = 24 • Thus, 163 is the wrong number.
General Intelligence Number Series Number Series Q. #6541 (CAT-I)
Find the incorrect number in the sequence: 8, 13, 21, 32, 47, 63, 83
A. 21
B. 13
C. 32
D. 47
Correct Answer: Option D
The difference between consecutive terms increases by 3: 8 + 5 = 13 13 + 8 = 21 21 + 11 = 32 32 + 14 = 46 (given as 47) 46 + 17 = 63 63 + 20 = 83 • Hence, the incorrect term is 47.
General Intelligence Number Series Number Series Q. #6540 (CAT-I)
Identify the wrong number in the following series: 19, 28, 39, 52, 67, 84, 102
A. 52
B. 102
C. 84
D. 67
Correct Answer: Option B
Let us examine the differences between successive numbers: 19 + 9 = 28 28 + 11 = 39 39 + 13 = 52 52 + 15 = 67 67 + 17 = 84 84 + 19 = 103 (instead of 102) • Therefore, 102 is the wrong number in the series.
General Intelligence Number Series Number Series Q. #6539 (CAT-I)
Find the missing term in the series: 3, 5, 9, ?, 33, 65
A. 17
B. 21
C. 23
D. 25
Correct Answer: Option A
The terms follow the pattern of powers of 2 plus 1 (2ⁿ + 1): 2¹ + 1 = 3 2² + 1 = 5 2³ + 1 = 9 2⁴ + 1 = 17 2⁵ + 1 = 33 2⁶ + 1 = 65 • Hence, the missing term is 17.
General Intelligence Number Series Number Series Q. #6538 (CAT-I)
Find the missing number in the given series: 19, 9, 28, 37, 65, ?
A. 99
B. 97
C. 102
D. 113
Correct Answer: Option C
Each term from the third term onward is the sum of the preceding two terms: 19 + 9 = 28 9 + 28 = 37 28 + 37 = 65 37 + 65 = 102 • Thus, the missing number is 102.
General Intelligence Number Series Number Series Q. #6537 (CAT-I)
Find the missing number in the following series: 1, 3, 6, 11, 18, ?
A. 25
B. 27
C. 29
D. 31
Correct Answer: Option C
The differences between consecutive numbers are consecutive prime numbers: 1 + 2 = 3 3 + 3 = 6 6 + 5 = 11 11 + 7 = 18 18 + 11 = 29 • Therefore, the missing term is 29.
General Intelligence Number Series Number Series Q. #6536 (CAT-I)
Find the missing term in the given sequence: 5, 13, 40, 104, ?
A. 217
B. 229
C. 259
D. 279
Correct Answer: Option B
The differences between consecutive terms are cubes of consecutive integers: 5 + 2³ = 5 + 8 = 13 13 + 3³ = 13 + 27 = 40 40 + 4³ = 40 + 64 = 104 104 + 5³ = 104 + 125 = 229 • Thus, the next number in the series is 229.
General Intelligence Number Series Number Series Q. #6535 (CAT-I)
What will replace the question mark (?) in the following series? 2, 3, 6, 7, 14, 15, ?
A. 16
B. 30
C. 31
D. 32
Correct Answer: Option B
The pattern alternates between adding 1 and multiplying by 2: 2 + 1 = 3 3 × 2 = 6 6 + 1 = 7 7 × 2 = 14 14 + 1 = 15 15 × 2 = 30 • Hence, the missing number is 30.
General Intelligence Number Series Number Series Q. #6534 (CAT-I)
Find the missing number in the series: 1, 2, 6, 12, 36, 72, ?
A. 108
B. 144
C. 180
D. 216
Correct Answer: Option D
The pattern follows alternating multiplication by 2 and 3: 1 × 2 = 2 2 × 3 = 6 6 × 2 = 12 12 × 3 = 36 36 × 2 = 72 72 × 3 = 216 • Therefore, the next number is 216.
