    As per the details of question is given series in the form of ,
    First series :-
    First term = 1260
    Second term = First term ÷ 2 - 2
    ⇒ Second term = 1260 ÷ 2 - 2 = 628
    Third term = Second term ÷ 2 - 2
    ⇒ Third term = 628 ÷ 2 - 2 = 312
    similarly , we can find the all others terms .
    ......... and so on .
    Second series :-
    First term = 788
    Second term = First term ÷ 2 - 2 = 392
    Third term = Second term ÷ 2 - 2 = 194

    Correct Option: B

    Third term = Second term ÷ 2 - 2
    ⇒ Third term = 392 ÷ 2 - 2 = 194
    Fourth term = Third term ÷ 2 - 2
    ⇒ Fourth term = 194 ÷ 2 - 2 = 95
    Fifth term = Fourth term ÷ 2 - 2
    ⇒ Fifth term = 95 ÷ 2 - 2 = 45.5
    Hence , the place value of ( d ) is 45.5 .

    As per the details in the question the series is in the form of
    First series :-
    First term = 5
    Second term = First term × 1 + 12 = 5 + 1 = 6
    Third term = Second term × 2 + 22 = 12 + 4 = 16
    similarly , we can calculate the all next terms .
    Second series :-
    First term = 2
    Second term = First term × 1 + 12 = 2 + 1 = 3
    Third term = Second term × 2 + 22 = 6 + 4 = 10

    Correct Option: E

    As per the details in the question the series is in the form of
    First series :-
    First term = 5
    Second term = First term × 1 + 12
    ⇒ Second term = 5 × 1 + 1 = 6
    Third term = Second term × 2 + 22
    ⇒ Third term = 6 × 2 + 4 = 16
    similarly , we can find the all others terms .
    Second series :-
    First term = 2
    Second term = First term × 1 + 12
    ⇒ Second term = 2 × 1 + 1 = 3
    Third term = Second term × 2 + 22
    ⇒ Third term = 3 × 2 + 4 = 10
    Fourth term = Third term × 3 + 32
    ⇒ Fourth term = 10 × 3 + 9 = 39
    Fifth term = Fourth term × 4 + 42
    ⇒ Fifth term = 39 × 4 + 16 = 172
    Hence , the place value of ( d ) is 172 .

    The given series is in the below pattern ,
    First series :-
    First term = 3
    Second term = First term × 2 - 1 = 5
    Third term = Second term × 2 - 1 = 9
    similarly , we can calculate the all next terms .
    Second series :-
    First term = 7
    Second term = First term × 2 - 1 = 13
    Third term = Second term × 2 - 1 = 25

    Correct Option: E

    The given series is in the below pattern ,
    First series :-
    First term = 3
    Second term = First term × 2 - 1
    ⇒ Second term = 3 × 2 - 1 = 5
    Third term = Second term × 2 - 1
    ⇒ Third term = 5 × 2 - 1 = 9
    similarly , we can find the all others terms .
    Second series :-
    First term = 7
    Second term = First term × 2 - 1
    ⇒ Second term = 7 × 2 - 1 = 13
    Third term = Second term × 2 - 1
    ⇒ Third term = 13 × 2 - 1 = 25
    Fourth term = Third term × 2 - 1
    ⇒ Fourth term = 25 × 2 - 1 = 49
    Fifth term = Fourth term × 2 - 1
    ⇒ Fifth term = 49 × 2 - 1 = 97
    Hence , the place value of ( d ) is 97 .

    The given series is in the below pattern ,
    First series :-
    First term = 5
    Second term = First term × 2 - 2 = 8
    Third term = Second term ÷ 2 + 2 = 6
    Fourth term = Third term × 2 - 2 = 10
    similarly , we can calculate the all next terms .
    ........... and so on.
    Second series :-
    First term = 7
    Second term = First term × 2 - 2 = 12
    Third term = Second term ÷ 2 + 2 = 8
    Fourth term = Third term × 2 - 2 = 14

    Correct Option: A

    The given series is in the below pattern ,
    First series :-
    First term = 5
    Second term = First term × 2 - 2
    ⇒ Second term = 5 × 2 - 2 = 8
    Third term = Second term ÷ 2 + 2
    ⇒ Third term = 8 ÷ 2 + 2 = 6
    Fourth term = Third term × 2 - 2
    ⇒ Fourth term = 6 × 2 - 2 = 10
    similarly , we can find the all others terms .
    ........... and so on.
    Second series :-
    First term = 7
    Second term = First term × 2 - 2
    ⇒ Second term = 7 × 2 - 2 = 12
    Third term = Second term ÷ 2 + 2
    ⇒ Third term = 12 ÷ 2 + 2 = 8
    Fourth term = Third term × 2 - 2
    ⇒ Fourth term = 8 × 2 - 2 = 14
    Hence , the place value of ( c ) is 14 .
