1 8 10 35 136 2 (a) (b) (c) (d) (e) Which of the following numbers will come in place of (c)?

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 .
