Correct Answer:

Explanation:

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 .
