6	3.0	4.5	2.25	4.0	12
40	(a)	(b)	(c)	(d)	(e)
Which of the following numbers will come in place of (c)?

The given series is in the below pattern ,
First series :-
First term = 6
Second term = First term ÷ 2
? Second term = 6 ÷ 2 = 3
Third term = Second term × 1.5
? Third term = 3 × 1.5 = 4.5
similarly , we can calculate the all next terms .
........... and so on.
Second series :-
First term = 40
Second term = First term ÷ 2
? Second term = 40 ÷ 2 = 20
Third term = Second term × 1.5
? Third term = 20 × 1.5 = 30
Fourth term = Third term ÷ 2
? Fourth term = 30 ÷ 2 = 15
Hence , the place value of (c) is 15 .
