2	3	6	15	45
16	(a)	(b)	(c)	(d)	(e)
Which of the following numbers will come in place of (d)?

As per the details in the question the series is in the form of
First series :-
First term = 2
Second term = First term × 1.5
? Second term = 2 × 1.5 = 3
Third term = Second term × 2
? Third term = 3 × 2 = 6
similarly , we can find the all others terms .
Second series :-
First term = 16
Second term = First term × 1.5
? Second term = 16 × 1.5 = 24
Third term = Second term × 2
? Third term = 24 × 2 = 48
Fourth term = Third term × 2.5
? Fourth term = 48 × 2.5 = 120
Fifth term = Fourth term × 3
? Fifth term = 120 × 3 = 360
Hence , the place value of ( d ) is 360 .
