This set of Verbal Reasoning Questions and Answers (MCQs) focuses on “Sequencing – Set 5”.
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 2 6 5 8 6 7 9 10 8 1 4 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 once i.e. ‘1 4 9’.
Hence, the answer is 1.
2. Identify the wrong number in the series. 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 45?
a) 8
b) 45
c) 20
d) 34
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 21+34 = 55. So the wrong number is 55.
Hence, the answer is 45.
3. Find the next number in the series: 63, 124, 215, 342, 511, …. ?
a) 824
b) 728
c) 951
d) 693
View Answer
Explanation: Here, each number is one less than cube of a number.
i.e. 43=64-1=63, 53=125-1=124, 63=216-1=215, 73=343-1=342, 83=512-1=511.
So, the next number will be 93=729-1=728.
Hence, the answer is 728.
4. Ankita’s younger brother Bobby is older than Nilu. Shweta is younger than Rahul but elder than Ankita. Who is the eldest?

a) 28
b) 64
c) 78
d) 62

7. Complete the following series 7, 14, 56, 448, 7168 …?
a) 685302
b) 803691
c) 229376
d) 409354
View Answer
Explanation: Here, the pattern followed is:-
7×2=14, 14×4=56, 56×8=448, 448×16=7168. Similarly, 7168×32=229376.
Hence, the answer is 229376.
8. Complete the following series 8, 24, 33, 49, 74…?
a) 110
b) 94
c) 106
d) 89
View Answer
Explanation: Here, the difference between the digits is the square of digits i.e.
24-8 = 16 = 42, 33-24 = 9 = 32, 49-33 = 16 = 42, 74-49 = 25 = 52.
Similarly, 110-74 = 36 = 62
Hence, the answer is 110.
9. Complete the following series 5, 10, 30, 120, 600…?
a) 8249
b) 6825
c) 3600
d) 2843
View Answer
Explanation: Here, the series follows the following pattern.
5×2=10, 10×3=30, 30×4=120, 120×5=600.
Similarly, 600×6=3600.
Hence, the answer is 3600.

a) 14th
b) 11th
c) 13th
d) 15th
View Answer
Explanation: Here, there are 30 boys and Harsh is in 9th position from left end after shifting. i.e. Harsh is in 15th position from left before shifting. So 30 – 15 = 15 i.e. there are 14 boys before Harsh, so his position was 15th from the right end.
Hence, the answer is 15th.
