3	5	22	13.5	35	19
1	(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 = 3
Second term = First term ÷ 2 + 3.5
? Second term = 3 ÷ 2 + 3.5 = 1.5 + 3.5 = 5
Third term = Second term × 2 + 12
? Third term = 5 × 2 + 12 = 10 + 12 = 22
similarly , we can find the all others terms .
Second series :-
First term = 1
Second term = First term ÷ 2 + 3.5
? Second term = 1 ÷ 2 + 3.5 = 0.5 + 3.5 = 4
Third term = Second term × 2 + 12
? Third term = 4 × 2 + 12 = 8 + 12 = 20
Hence , the place value of ( a ) is 4 .
