3 5 22 13.5 35 19 1 (a) (b) (c) (d) (e) Which of the following numbers will come in place of (a) ?
-
- 3
- 2
- 5
- 4
- None of these
Correct Option: D
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 .
