    As per the details in the question the series is in the form of
    First series :-
    First term = 7
    Second term = First term × 0.5 + 0.5 = 4
    Third term = Second term × 1 + 1 = 5
    similarly , we can calculate the all next terms .
    Second series :-
    First term = 3
    Second term = First term × 0.5 + 0.5 = 2
    Third term = Second term × 1 + 1 = 3

    Correct Option: C

    As per the details in the question the series is in the form of
    First series :-
    First term = 7
    Second term = First term × 0.5 + 0.5
    ⇒ Second term = 7 × 0.5 + 0.5 = 4
    Third term = Second term × 1 + 1
    ⇒ Third term = 4 × 1 + 1 = 5
    similarly , we can find the all others terms .
    Second series :-
    First term = 3
    Second term = First term × 0.5 + 0.5
    ⇒ Second term = 3 × 0.5 + 0.5 = 2
    Third term = Second term × 1 + 1
    ⇒ Third term = 2 × 1 + 1 = 3
    Fourth term = Third term × 1.5 + 1.5
    ⇒ Fourth term = 3 × 1.5 + 1.5 = 6
    Hence , the place value of ( c ) is 6 .

    The series is × 2 – 2, × 3 + 2, × 4 – 2,...
    The given series is in the below pattern ,
    First series :-
    First term = 6
    Second term = First term × 2 - 2 = 10
    Third term = Second term × 3 + 2 = 32
    similarly , we can calculate the all next terms .
    Second series :-
    First term = 2
    Second term = First term × 2 - 2
    Third term = Second term × 3 + 2

    Correct Option: C

    The given series is in the below pattern ,
    First series :-
    First term = 6
    Second term = First term × 2 - 2
    ⇒ Second term = 6 × 2 - 2 = 10
    Third term = Second term × 3 + 2
    ⇒ Third term = 10 × 3 + 2 = 32
    similarly , we can find the all others terms .
    ......... and so on .
    Second series :-
    First term = 2
    Second term = First term × 2 - 2
    ⇒ Second term = 2 × 2 - 2 = 2
    Hence , the place value of ( a ) is 2 .

Direction: Read the given series and complete this series.

    The given series is in the below pattern,
    1st letter moves +2, +3 and +4 steps respectively.
    2nd letter moves –2, –3 and –4 steps respectively.

    Correct Option: B

    The given series is in the below pattern,
    1st letter moves +2, +3 and +4 steps respectively.
    2nd letter moves –2, –3 and –4 steps respectively.
    Hence the place value of ? is JQ .
