Letter Series Involving Vowels

Position of Vowels :  Vowels are the letters A, E, I, O, and U. The other letters in the alphabet are called consonants.

Using Vowels in Letter Series :

Illustration 1 : What will come in place of the question mark (?) in the given series?     U, O, I, ?,  A

(a) E               (b) C                     (c) S                          (d) G

Answer : (a)

Explanation : The series consists of vowels A, E, I, O and U written in the reverse order.

Illustration 2 : What will come in place of the question mark (?) in the given series?    A, A, C, E, E, I, G, ?

(a) H                    (b) U                 (c) O                (d) J

Answer : (c)

Explanation : This question contains two series which are as follows :

  • Series 1 : A, C , E , G.... this clearly shows that one alphabet is skipped in between two terms.
  • Series 2 : A, E , I , ? .... Thus clearly represents the series of vowels.
  • Hence, the next term is O.

    Illustration 3 : What will come in place of the question mark (?) in the given series?

    Z,U,X,?,?,I,T,E,R,A,P

    (a) O,V   (b) A, C    (c) V,O     (d) O,U

    Answer : (a)

    Explanation : This question contains two series which are as follows :

    Series 1 : Z, X, ?, T, R, P

    Series 2 : U, ?, I, E, A

    Series 1 contains the letters having 2 difference.

     Z(26), X(24),V(22), T(20), R(18), P(16)

    Series 2 contains vowels in reverse   manner.

    U,O,I,E,A 

    So, the missing letters are O,V.

    Illustration 4 : What will come in place of the question mark (?) in the given series?

    A,U,E,O,?,?,O,E,U,A   

    (a)  A,I     (b)  I,A     (c)  I,I    (d)  A,A

    Answer : (c)

    Explanation :   This question contains two series which are as follows :

    Series 1 : A,E,I,O,U 

    The above series contains vowels.

    Series 2 : U,O,I, E,A  

    The above series contains vowels but in reverse manner.

    So, we finds that the missing letters are I,I.

    Illustration 5 : What will come in place of the question mark (?) in the given series?

    B,A,F,E, ?, ?, ?, O, R,U,V

    (a) J,I,N     (b) N,J,I    (c) I,J,N    (d) None of these

    Answer : (a)

    Explanation :  This question contains two series which are as follows :

    Series 1 : B(2), F(6), J(10), N(14), R(18), V(22)

    The above series have the difference of 4.

    Series 2 : A,E,I,O,U

    The above series contains vowels.

    So, the missing letters are J,I,N.
