Correct Answer: 17

Explanation:

The given series is in the below pattern,
First term = 16
Second term = First term + 1²
? Second term = 16 + 1² = 17
? ? = 17
Third term = Second term + 2²
? Third term = 17 + 2² = 21
Fourth term = Third term + 3²
? Fourth term = 21 + 3² = 30 ;
Fifth term = Fourth term + 4²
? Fifth term = 30 + 4² = 46 ;
Similarly , we can find all others terms also.
Sixth term = Fifth term + 5²
? Sixth term = 46 + 5² = 71;
Seventh term = Sixth term + 6²
? Sixth term = 71 + 6² = 107
Hence , Second term = 17

Correct Answer: 4

Explanation:

The given series is in the below pattern ,
First series :-
First term = 3
Second term = First term ÷ 2 + 3.5
? Second term = 3 ÷ 2 + 3.5 = 1.5 + 3.5 = 5
Third term = Second term × 2 + 12
? Third term = 5 × 2 + 12 = 10 + 12 = 22
similarly , we can find the all others terms .
Second series :-
First term = 1
Second term = First term ÷ 2 + 3.5
? Second term = 1 ÷ 2 + 3.5 = 0.5 + 3.5 = 4
Third term = Second term × 2 + 12
? Third term = 4 × 2 + 12 = 8 + 12 = 20
Hence , the place value of ( a ) is 4 .
