Direction: In each of the following questions a number series is given. A number is given after the series and then (a), (b), (c), (d) and (e) are given. According to the given series, you have to form a new series which begins with the given number, and then answer the question asked.
-
2 3 6 15 45 16 (a) (b) (c) (d) (e) Which of the following numbers will come in place of (d) ?
-
- 360
- 120
- 300
- 240
- None of these
Correct Option: A
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 .
