Inserting and Missing Character
This chapter is based on series of letters.
In this type of questions, a series of single, pairs or groups of letters or combinations of letters and numbers is given. Candidate is required to recognize this pattern and accordingly find the missing terms or the wrong terms. To understand this chapter or to perform well, one has to understand the following concept of values or relationship between Alphabets and Numerals.
In this series only letters are available which follow a certain pattern throughout. Candidate has to recognize this pattern and to give the required answer.
Position of Letters:
First of all, we should know the position of all the letters form A to Z.
Position of Opposite Letters:
It is also recommended, that one must Remember
This will help you to understand the concept or to find out the values of Alphabets without finding or writing all the alphabets with their respective values.
Example- A, E, I, M, Q, ?
Solution:- A→ E→ I→ M→ Q→? = (U)
As the pattern is the gap between the letters is +4. So required letter is U.
Example- 1, A, 4, D, 7, G, 10,?
Solution:- As we follow the pattern we found that the difference between the numbers is 3 and the difference between the alphabets is also three. So next be J.
Example- C2E, E5H, G12K, 127N,?
(a) I58P (b) J58Q (c) K58Q (d) I57Q
Solution:- The series follows for patterns.
Direction: A series is given, with one term missing. Choose the correct alternative from the given ones that will complete the series.
Ex. BCFG, JKNO, RSVW, ?
Solution:- Correct Option (a)
B, C, F, G
2, 3, 6, 7
J, K, N, O
R, S, V, W
Next sequence = 26, 27, 30, 31 = 26, 1, 4, 5 = Z A D E
(subtract the excess value by 26)
