Series Completion Questions Answers (MCQ) of Verbal Reasoning includes questions to complete the series by identifying the pattern of series which are important for all competitive exams.

21) Which fraction will come next, \begin{aligned} \frac{1}{2}, \frac{3}{4}, \frac{5}{8}, \frac{7}{16}, ? \end{aligned}

• 1) \begin{aligned} \frac{11}{32} \end{aligned}
• 2) \begin{aligned} \frac{9}{28} \end{aligned}
• 3) \begin{aligned} \frac{9}{30} \end{aligned}
• 4) \begin{aligned} \frac{9}{32} \end{aligned}
Ans.   D
Explanation :
Numerators of the fractions in the given sequence are getting increased by 2, i.e. 1+2,3+2,5+2, so next will be 7+2 = 9 Denominators of the fractions in the series is getting doubled, 2*2 = 4, 4*2 = 8, 8*2 = 16, no next will be 16*2 = 32 So resulting fraction will be \begin{aligned} \frac{9}{32} \end{aligned}

22) 1,9,17,33,49,73,

• 1) 93
• 2) 95
• 3) 97
• 4) 99
Ans.   C
Explanation :
Pattern for the given series is, +8, +8, +16, +16, +24 So next will be +24, 73+24 = 97

23) 2,5,9,?,20,27, what will replace the question mark

• 1) 13
• 2) 14
• 3) 15
• 4) 16
Ans.   B
Explanation :
Pattern is +3,+4,..,..,+7, so +5 and +6 will be in the blanks Question mark will be replaced by 9+5 = 14

24) 21,25,33,49,81

• 1) 140
• 2) 145
• 3) 147
• 4) 159
Ans.   B
Explanation :
Pattern is, +4, +8, +16, +32, so next will be +64 81+64 = 145

25) 5,9,17,29,45

• 1) 50
• 2) 60
• 3) 65
• 4) 70
Ans.   C
Explanation :
In this series the pattern is +4, +8, +12, +16, so next will be +20 Term which will replace the question mark in this series will be 45+20 = 65

26) 1,6,15,(...),45,66

• 1) 26
• 2) 28
• 3) 29
• 4) 34
Ans.   B
Explanation :
Pattern in the series is, +5, +9, .., .., +21, +25 So 4 is getting increased at every term addition. Missing term in the series will be 15+(9+4) = 15+13 = 28

27) Look at this series: 22, 21, 23, 22, 24, 23, ... What number should come ne

• 1) 25
• 2) 26
• 3) 27
• 4) 28
Ans.   A
Explanation :
Please look carefully at the series, its pattern is, -1, +2, -1, +2, -1, so next will be +2 23+2 = 25

28) What number should come next in the series, 1, 2, 3, 5, 8

• 1) 17
• 2) 12
• 3) 9
• 4) 13
Ans.   D
Explanation :
In this series, each term is the sum of preceding two terms as, 1+2 = 3 3+2 = 5 5+3 = 8 Next term in the series will be, 8+5 = 13

29) 1, 2, 5, 12, 27, 58, 121

• 1) 248
• 2) 244
• 3) 198
• 4) 190
Ans.   A
Explanation :
Pattern in the series is *2+1, *2+2, *2+3,..... Term which replaces the question mark in the series is 121 * 2 + 6 = 248

30) Complete the series, 3, 8, 13, 24, 41

• 1) 70
• 2) 66
• 3) 64
• 4) 62
