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
⇒ Second term = 788 ÷ 2 - 2 = 392
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 .
