Q6: Direction: In the following question, a series is given. A term in series is missing. Find the missing term from amongst the options.
18, 17, 19,?, 20, 15, 21, 14
(a) 16
(b) 17
(c) 18
(d) 19
Ans: (a) 16
Explanation: Observing the sequence, it appears that the numbers are alternating between increasing and decreasing. Specifically, the pattern seems to be:
Subtract 1
Add 2
Subtract 3
Add 4
Following this pattern:
18  1 = 17
17 + 2 = 19
19  3 = 16
(16) + 4 = 20
20  1 = 19
19 + 2 = 21
21  3 = 18
(18) + 4 = 22
So, the missing term in the sequence should be 16. Therefore, the correct answer is A) 16.
Q7: Direction: In the following question, a series is given. A term in series is missing. Find the missing term from amongst the options.
1, 5, 13, 25, 41, ?
(a) 52
(b) 58
(c) 61
(d) 62
Ans: (b) 58
Explanation: Observing the sequence, it appears that the numbers are increasing in a specific pattern. Let's analyze the differences between consecutive terms:
It seems like the differences are increasing by 4 each time. Therefore, following this pattern:
The difference between the next term and 41 should be 16 + 4 = 20.
So, to find the missing term:
41 (last term) + 20 = 61.
Therefore, the correct answer is C) 61.
Q8: Direction: In the following question, a series is given. A term in series is missing. Find the missing term from amongst the options.
10, 18, 28, 40, 54, 70,?
(a) 85
(b) 86
(c) 87
(d) 88
Ans: (d) 88
Explanation: To find the pattern in the given sequence, let's analyze the differences between consecutive terms:
It appears that the differences are increasing by 2 each time. Following this pattern:
The difference between the next term and 70 should be 16 + 2 = 18.
So, to find the missing term:
70 (last term) + 18 = 88.
Therefore, the correct answer is D) 88.
Q9: Direction: In the following question, a series is given. A term in series is missing. Find the missing term from amongst the options.
6, 11, 21, 36, 56,?
(a) 42
(b) 51
(c) 81
(d) 91
Ans: (c) 81
Explanation: To identify the pattern in the given sequence, let's examine the differences between consecutive terms:
It appears that the differences are increasing by 5 each time. Following this pattern:
The difference between the next term and 56 should be 20 + 5 = 25.
So, to find the missing term:
56 (last term) + 25 = 81.
Therefore, the correct answer is C) 81.
Q10: Direction: In the following question, a series is given. A term in series is missing. Find the missing term from amongst the options.
2, 5, 9, ?, 20, 27
(a) 14
(b) 16
(c) 18
(d) 24
Ans: (a) 14
Explanation: To identify the pattern in the given sequence, let's examine the differences between consecutive terms:
It appears that the differences are increasing by 1 each time. Following this pattern:
The difference between the next term and 9 should be 4 + 1 = 5.
So, to find the missing term:
9 (last term) + 5 = 14.
Therefore, the correct answer is A) 14.
