Sequences (IQ)

1, 1, 2, 3, 5, 8, ?

• 12

• 13

• 16

• 10

• None of these

Answer explanation

The sequence is the Fibonacci series, where each number is the sum of the two preceding ones. After 1, 1, 2, 3, 5, and 8, the next number is 5 + 8 = 13.

7, 12, 19, 31, 50, ?

• 83

• 79

• 80

• 81

• None of these

27, 35, 47, 63, 83, ?

• 105

• 107

• 114

• 111

• None of these

108, 120, 138, 162, 192, ?

• 196

• 228

• 206

• 219

• None of these

Answer explanation

The pattern in the sequence involves increasing differences: 12, 18, 24, 30, leading to a difference of 36 for the next term. Thus, 192 + 36 = 228, making it the correct answer.

11, 53, 93, 131, 167, ?

• 162

• 174

• 181

• 201

• None of these

Answer explanation

The pattern in the sequence is an increasing difference: +42, +40, +38, +36, leading to +34 for the next term. Thus, 167 + 34 = 201, making the correct answer 201.

156, 145, 123, 90, 46, ?

• 3

• -1

• -7

• -9

• None of these

Answer explanation

The pattern in the sequence shows a decreasing trend: 156-11=145, 145-22=123, 123-33=90, 90-44=46. Continuing this pattern, 46-55= -9. Thus, the next number is -9.

5000, 1000, 200, 40, 8, ?

• 2.3

• 3.2

• 0.8

• 1.4

• None of these

Answer explanation

The sequence divides by 5, then by 5, then by 5, then by 5, leading to 1.6. None of the answer choices match this result, so the correct answer is 'None of these'.

8. 7, 14, 5, 13, 2, 11, -2, 8, ?

• 11

• 4

• 7

• -4

• -7

144, 153, 171, 207, 279, ?

• 423

• 411

• 453

• 397

• None of these

Answer explanation

The pattern in the sequence involves increasing differences: 9, 18, 36, 72, leading to the next difference of 144. Adding 144 to 279 gives 423, which is the next number in the series.

10, 22, 46, 94, ?, 382

• 112

• 128

• 149

• 167

• None of these

Answer explanation

The pattern in the sequence involves doubling the previous number and then adding a specific increment. Following this pattern, the missing number should be 256, which is not among the answer choices. Thus, the correct answer is 'None of these'.
