Semantic Series

A semantic series is a process of finding the relation from the pair that is given and then applying that relationship to find the unknown terms. The semantic series question includes the alphabetical series, numerical series, arithmetic series, geometric series, and others. It can also be seen as the mixture of 2 completely different series. This merged series is often given in the exam to test the students because it confuses those who are facing such questions for the first time.

Semantic Series MCQ

Every question of the Semantic series has multiple choices available, but it is most preferred that a student must find the relation between the terms already given and then use that connection to find the relation between the next term and the given series last term.

Semantic Series Reasoning Tricks

Although semantic series is an important topic in government job exams, there is no specific method to solve a question related to semantic series. Thus, questions related to semantic series can only be solved by regressive practice.

One of the key points while answering questions related to semantic series is that an answer should never be guessed. Because, in most cases, the questionnaire has the options which look like they are the correct choices, but it is a trap; therefore, the answer should never be guessed.

Semantic Series Questions

Q1. A, D, H, M, ?

1. R
2. S
3. T
4. V

The solution to such questions can be found by making an alphabetical table as shown below:

Now as we can see that the difference between A and D is 2, between D and H is 3, and between H and M is 4. Therefore, the difference between the last terms and M will be 5, which means that the letter which will replace the question mark will be S.

Q2. 1, 8, 27,?

1. 36
2. 49
3. 64
4. 125

The series is semantic and is a series of cubic numbers. Therefore, the question mark can be replaced by a cube of 4.

Hence, the question mark can be replaced by 64.

Q3. A1, B3, C5, D7, ?

1. E9
2. F9
3. G10
4. E10

The relation between the terms is that the alphabet is increasing by one, while the number is increasing by two.

Thus, a term that can replace the question mark can be written as

D(+1)E

7(+2)9

Hence, the term that can replace the question mark is E9.

Q4. 25, 36, 49 ,64, ?

1. 81
2. 100
3. 92
4. 98

The series is a series of squares; therefore, it can be seen as,

25, 36, 49, 64, = 52, 62, 72, 82,

Thus, the term that can replace the question mark is 92 or can be seen as 81.

Q5. 2, 1, 0.5, 0.25,?

1. 0.75
2. 0.125
3. 0.05
4. 0.20

In this series, every term of the series will get half of the previous term. Hence, the terms of the series can be seen as

2221

1120.5

0.50.520.5

0.50.520.25

The next term of the series, which can replace the question mark, can be written as,

0.250.2520.125

Hence, the term that can replace the question mark is 0.125.

Q.6  5, 2, 10, 4, 15, 6, ?

1. 8
2. 20
3. 9
4. 10

The series given is a special series and is a mixture of two different series. The two different series can be seen as,

51015 This series increases by 5 in every next term.

246 This series increases by 2.

Now, in the main series, it can be seen as the first term of the main series is from the series increasing by 5; therefore, it can be concluded that every odd positioned term will be from the series increasing by 5.

Also, in the main series, it can be seen as the second term of the main series is from the series increasing by 2; therefore, it can be concluded that every even positioned term will be from the series increasing by 2.

Since the question mark is at 7th position, the next term will be from the series increasing by 5. Therefore, the next term can be written as

5101520

Hence, the correct option is B which is 20.

Conclusion

Semantic series questions are questions of series where the student needs to find the relation between the given terms of the series and then use that relationship to find the unknown term of the series. It is one of the most important questions in any government exam and is easy to solve. The only key to solving such a question is to do regressive practice from different sources.
