6	10	32	126
2	(a)	(b)	(c)	(d)	(e)
Which of the following numbers will come in place of (a)?

Correct Answer: 79

Explanation:

The given series is in the below pattern ,
First series :-
First term = 4
Second term = First term × 2 + 1
? Second term = 4 × 2 + 1 = 9
Third term = Second term × 3 - 2
? Third term = 9 × 3 - 2 = 25
similarly , we can find the all others terms .
......... and so on .
Second series :-
First term = 3
Second term = First term × 2 + 1
? Second term = 3 × 2 + 1 = 7
Third term = Second term × 3 - 2
? Third term = 7 × 3 - 2 = 19
Fourth term = Third term × 4 + 3
? Fourth term = 19 × 4 + 3 = 79
Hence , the place value of ( c ) is 79 .

Correct Answer:

Explanation:

The given series is in the below pattern ,
First series :-
First term = 6
Second term = First term ÷ 2
? Second term = 6 ÷ 2 = 3
Third term = Second term × 1.5
? Third term = 3 × 1.5 = 4.5
similarly , we can calculate the all next terms .
........... and so on.
Second series :-
First term = 40
Second term = First term ÷ 2
? Second term = 40 ÷ 2 = 20
Third term = Second term × 1.5
? Third term = 20 × 1.5 = 30
Fourth term = Third term ÷ 2
? Fourth term = 30 ÷ 2 = 15
Hence , the place value of (c) is 15 .

Correct Answer: QRN

Explanation:

The first letters of the terms are consecutive letters. The third letter of each term is moved three steps backward to obtain the third letter of the successive term. The middle letters of the first, second, third and fourth terms are moved one, two, three, and four steps forward respectively to obtain the middle letter of the successive terms.
The order of above series given as - + 1 , + 2 , - 3
MHZ, NIW, OKT, PNQ, ( ? )
So ? = QRN ? 17 18 14
Hence , required answer will be QRN .

Correct Answer: SXI

Explanation:

As per the details in the question the series is in the form of
The first letters of the terms are in alphabetical order, and so are the second and third letters.
Hence required answer will be SXI .

Correct Answer: JQ

Explanation:

The given series is in the below pattern,
1st letter moves +2, +3 and +4 steps respectively.
2nd letter moves ?2, ?3 and ?4 steps respectively.
Hence the place value of ? is JQ .

Correct Answer: 6

Explanation:

As per the details in the question the series is in the form of
First series :-
First term = 7
Second term = First term × 0.5 + 0.5
? Second term = 7 × 0.5 + 0.5 = 4
Third term = Second term × 1 + 1
? Third term = 4 × 1 + 1 = 5
similarly , we can find the all others terms .
Second series :-
First term = 3
Second term = First term × 0.5 + 0.5
? Second term = 3 × 0.5 + 0.5 = 2
Third term = Second term × 1 + 1
? Third term = 2 × 1 + 1 = 3
Fourth term = Third term × 1.5 + 1.5
? Fourth term = 3 × 1.5 + 1.5 = 6
Hence , the place value of ( c ) is 6 .

Correct Answer: 46

Explanation:

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 .

Correct Answer: 49

Explanation:

The series is × 2 ?1, × 3 ? 2, × 4 ? 3,.....
The given series is in the below pattern ,
First series :-
First term = 2
Second term = First term × 2 - 1
? Second term = 2 × 2 - 1 = 3
Third term = Second term × 3 - 2
? Third term = 3 × 3 - 2 = 7
similarly , we can calculate the all next terms .
Second series :-
First term = 3
Second term = First term × 2 - 1
? Second term = 3 × 2 - 1 = 5
Third term = Second term × 3 - 2
? Third term = 5 × 3 - 2 = 13
Fourth term = Third term × 4 - 3
? Fourth term = 13 × 4 - 3 = 49
Hence , the place value of ( c ) is 49 .

Correct Answer:

Explanation:

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 .

Correct Answer:

Explanation:

As per the details in the question the series is in the form of
First series :-
First term = 9
Second term = First term × 2 + 1.5 = 19.5
Third term = Second term × 2 + 2 = 41
similarly , we can calculate the all next terms .
Second series :-
First term = 12
Second term = First term × 2 + 1.5 = 25.5
Third term = Second term × 2 + 2 = 53
Fourth term = Third term × 2 + 2.5
? Fourth term = 53 × 2 + 2.5 = 108.5
So, 108.5 should come in place of (c).
