? Second term = 5 × 1 + 4 = 9
Third term = Second term × 2 + 8
? Third term = 9 × 2 + 8 = 26
similarly , we can find the all others terms .
......... and so on .
Second series :-
First term = 13
Second term = First term × 1 + 4
? Second term = 13 × 1 + 4 = 17
Third term = Second term × 2 + 8
? Third term = 17 × 2 + 8 = 42
Fourth term = Third term × 3 + 12
? Fourth term = 42 × 3 + 12 = 138
Fifth term = Fourth term × 4 + 16
? Fifth term = 138 × 4 + 16 = 568

Correct Answer: 66

Explanation:

As per the details in the question the series is in the form of
First term + Second term = Third term
? 7 + 9 = 16;
Second term + Third term = Fourth term
? 9 + 16 = 25;
Similarly , we can find all others terms also.
Third term + Fourth term = Fifth term
? 16 + 25 = 41;
Fourth term + Fifth term = Sixth term
? 25 + 41 = ?
? ? = 66
Fifth term + Sixth term = Seventh term
? 41 + 66 = 107
Sixth term + Seventh term = Eighth term
? 66 + 107 = 173
Hence , Sixth term = 66

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 .

Correct Answer: 88.5

Explanation:

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 .
