  1. 3123066138282
    7(a)(b)(c)(d)(e)
    Which of the following numbers will come in place of (b) ?
    1. 34
    2. 70
    3. 46
    4. 62
    5. None of these
Correct Option: C

As per the details in the question the series is in the form of
First series :-
First term = 3
Second term = First term × 2 + 6
Second term = 3 × 2 + 6 = 12
Third term = Second term × 2 + 6
Third term = 12 × 2 + 6 = 30
similarly , we can find the all others terms .
Second series :-
First term = 7
Second term = First term × 2 + 6
Second term = 7 × 2 + 6 = 20
Third term = Second term × 2 + 6
Third term = 20 × 2 + 6 = 46
Hence , the place value of ( b ) is 46 .
