This set of Verbal Reasoning Questions and Answers (MCQs) focuses on “Sequencing – Set 10”.

1. How many odd numbers are there in the following series of numbers, each of which is immediately preceded by an even number, but not immediately followed by an odd number?
7 2 8 9 1 3 4 5 7 5 8 9 6 9 1 8 2 4 9 2 6
a) 1
b) 2
c) 3

2. Identify the missing number in the series. 233, 144, 89, 55, 34, ?, 13?
a) 29
b) 25
c) 21
d) 23

Explanation: Here, the series is a reversed Fibonacci series.
i.e. a number in the series is the difference of previous two numbers.
So, in this missing number is 55-34 =21.

3. Find the next number in the series : 5, 122, 509, 1328, …. ?
a) 1824
b) 2741
c) 2329
d) 1693

Explanation: Here, each number is three less than cube of a number.
i.e. 23=8-3=5, 53=125-3=122, 83=512-3=509, 113=1331-3=1328.
So, the next number will be 143=2744-3=2741.

a) 608
b) 534
c) 393
d) 557

19×2=38, 38×2=76, 76×2=152, 152×2=304. Similarly, 304×2=608.

8. Complete the following series 162, 243, 307, 356, 392….?
a) 114
b) 273
c) 417
d) 389

Explanation: Here, the difference between the digits is the square of digits i.e.
243-162 = 81 = 92, 307-243 = 64 = 82, 356-307 = 49 =72, 392-356 = 36 = 62.
Similarly, 417-392 = 25 = 52

9. Complete the following series 8, 26, 106, 532…?
a) 3194
b) 6825
c) 1957
d) 2843

3×2=6+2=8, 8×3=24+2=26, 26×4=104+2=106, 106×5=530+2=532.
Similarly, 532×6=3192+2=3194.

10. In a row of 32 boys, when Tushar shifted twelve places towards the right, he become 12th from the right end. What was his earlier position form the left end of the row?
