6	10	32	126
2	(a)	(b)	(c)	(d)	(e)
Which of the following numbers will come in place of (a)?

The given series is in the below pattern ,
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 :-
First term = 2
Second term = First term × 2 - 2
? Second term = 2 × 2 - 2 = 2
Hence , the place value of ( a ) is 2 .
