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 :-

Second term = First term × 2 - 2
Second term = 2 × 2 - 2 = 2
Hence , the place value of ( a ) is 2 .
