This set of Verbal Reasoning Questions and Answers (MCQs) focuses on “Sequencing – Set 7”.
1. How many even numbers are there in the following series of numbers, each of which is immediately preceded by an odd number, but not immediately followed by an even number?
6 2 8 9 1 3 4 5 7 5 8 6 7 9 3 8 1 5 9 2 6
a) 1
b) 2
c) 3
d) 4
View Answer
Explanation: Here, we are looking for a group of numbers i.e. odd even odd. In the series it only occurs twice i.e. ‘3 8 1’, ‘3 4 5’.
Hence, the answer is 2.
2. Identify the wrong number in the series. 21, 34, 55, 89, 144, 234, 377?
a) 89
b) 55
c) 234
d) 377
View Answer
Explanation: Here, the series is a Fibonacci series.
i.e., a number in the series is the sum of previous two numbers.
So, in this 89+144 = 233. So the wrong number is 234.
Hence, the answer is 234.
3. Find the next number in the series: 26, 124, 342, 728, …. ?
a) 1824
b) 1728
c) 1330
d) 1693
View Answer
Explanation: Here, each number is one less than cube of a number.
i.e., 33=27-1=26, 53=125-1=124, 73=343-1=342, 93=729-1=728.
So, the next number will be 113=1331-1=1330.
Hence, the answer is 1330.

7. Complete the following series 13, 26, 104, 832, 13312 …?
a) 685302
b) 425984
c) 393216
d) 409354
View Answer
Explanation: Here, the pattern followed is:-
13×2=26, 26×4=104, 104×8=832, 832×16=13312. Similarly, 13312×32=425984.
Hence, the answer is 425984.
8. Complete the following series 13, 38, 74, 123, 187…?
a) 110
b) 268
c) 106
d) 382
View Answer
Explanation: Here, the difference between the digits is the square of digits i.e.
38-13 = 25 = 52, 74-38 = 36 = 62, 123-74 = 49 =72, 187-123 = 64 = 82.
Similarly, 268-187 = 81 = 92
Hence, the answer is 268.
9. Complete the following series 3, 6, 18, 72, 360…?
a) 8249
b) 6825
c) 6480

9×2=18, 18×3=54, 54×4=216, 216×5=1080.
Similarly, 1080×6=6480.
Hence, the answer is 6480.
10. In a row of 19 boys, when Ram shifted three places towards the left, he become 10th from the left end. What was his earlier position form the right end of the row?
a) 4th
b) 7th
c) 6th
d) 5th
View Answer
Explanation: Here, there are 19 boys and Ram is in 10th position from left end after shifting. i.e. Ram is in 13th position from left before shifting. So 19 – 13 = 6 i.e. there are 6 boys before Ram, so his position was 7th from the right end.
Hence, the answer is 7th.
