Q 10 − Three of the following four are alike in a certain way based on their position in the above arrangement. Which of the following does not belong to the group?
In the above sequence, we can see that there are numbers, alphabets, and symbols. These types of sequences are called alphanumeric sequence. We can make many sequences like this and can deduce questions based on the sequences.
Important Points to Remember
Let’s have an alphanumeric sequence −
A $ E R 9 * T 5 F 6 @ D 8
Questions regarding this chapter can come in this way −
a. Which element is nth from the left of the sequence?
b. Which element is nth from the right of the sequence?
c. Which element is mth to the right of nth from the left of the sequence?
d. Which element is mth to the left of nth from the left of the sequence?
e. Which element is mth to the right of nth from the right of the sequence?
f. Which element is mth to the left of nth from the right of the sequence?
g. A precedes B
h. B is preceded by A
i. B follows A
j. A is followed by B
To solve questions like this, we have to watch the sequence thoroughly and answer accordingly.
a. Which element is nth from the left of the sequence?
To get the answer of the above question, we have to look at the sequence from the left side and have to count the exact number that is asked in the question.
b. Which element is nth from the right of the sequence?
To get the answer of the above question, we have to look at the sequence from the right side and have to count the exact number that is asked in the question.
c. Which element is mth to the right of nth from the left of the sequence?
To get the answer for such type of questions, we have to find out the nth element from the left side of the sequence and then find out the mthelement to the right of that particular element.
d. Which element is mth to the left of nth from the left of the sequence?
To get the answer for such type of questions, we have to find out the nth element from the left side of the sequence and then find out the mthelement to the left of that particular element.
e. Which element is mth to the right of nth from the right of the sequence?
To get the answer for such type of questions, we have to find out the nth element from the right side of the sequence and then find out the mth element to the right of that particular element.
f. Which element is mth to the left of nth from the right of the sequence?
To get the answer for such type of questions, we have to find out the nth element from the right side of the sequence and then find out the mth element to the left of that particular element.
g. If it is written that A precedes B then it means A is placed before B.
h. Similarly if it is written that B is preceded by A then it means A is placed before B.
i. If it is written that B follows A then it means B is placed after A.
j. If it is written that A is followed by B then B is placed after A.
These ten type of questions are normally asked in this chapter. Whether it is of a type or b type or c type or j type we have to read the question carefully and see the sequence and finally we can get the answer according to the question.
