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.
-
1 8 10 35 136 2 (a) (b) (c) (d) (e) Which of the following numbers will come in place of (c) ?
-
- 40
- 42
- 51
- 49
- None of these
Correct Option: E
As per the details in the question the series is in the form of
First series :-
First term = 1
Second term = First term × 1 + 7
⇒ Second term = 1 × 1 + 7 = 8
Third term = Second term × 2 - 6
⇒ Third term = 8 × 2 - 6 = 10
similarly , we can find the all others terms .
Second series :-
First term = 2
Second term = First term × 1 + 7
⇒ Second term = 2 × 1 + 7 = 9
Third term = Second term × 2 - 6
⇒ Third term = 9 × 2 - 6 = 12
Fourth term = Third term × 3 + 5
⇒ Fourth term = 12 × 3 + 5 = 41
Hence , the place value of ( c ) is 41 .
