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.
-
17 21.5 30.5 44 62 21 (a) (b) (c) (d) (e) Which of the following numbers will come in place of (e) ?
-
- 84.5
- 88.5
- 86
- 88
- None of these
Correct Option: B
The given series is in the below pattern ,
First series :-
First term = 17
Second term = First term + 4.5
⇒ Second term = 17 + 4.5 = 21.5
Third term = Second term + 9
⇒ Third term = 21.5 + 9 = 30.5
similarly , we can find the all others terms .
Second series :-
First term = 21
Second term = First term + 4.5
⇒ Second term = 21 + 4.5 = 25.5
Third term = Second term + 9
⇒ Third term = 25.5 + 9 = 34.5
Fourth term = Third term + 13.5
⇒ Fourth term = 34.5 + 13.5 = 48
Fifth term = Fourth term + 18
⇒ Fifth term = 48 + 18 = 66
Sixth term = Fifth term + 22.5
⇒ Sixth term = 66 + 22.5 = 88.5
Hence , the place value of ( e ) is 88.5 .
