    Explanation

    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 .
