Accepted Answer

The given number series follows a pattern that, 19 + 1 2 = 20 ( not 21 ) 20 + 2 2 = 24 24 + 3 2 = 33 33 + 4 2 = 49 49 + 5 2 = 74 Hence, the odd number in the given number series is 21.

Question 5

Complete the given number series? 8, 14, 24, 40, ?

Accepted Answer

The given number series is 8, 14, 24, 40, ? . It follows a pattern that, 8 8 x 1.5 + 2 = 14 14 x 1.5 + 3 = 24 24 x 1.5 + 4 = 40 40 x 1.5 + 5 = 65 Hence, the next number in the given number series is 65.

Question 6

Find the next number in the given sequence? 11, 17, 39, 85, ?

Accepted Answer

Her the given number series is 11, 17, 39, 85, ? 11 11 + 3 2 - 3 = 17 17 + ( 5 2 - 3 ) = 39 39 + ( 7 2 - 3 ) = 85 85 + ( 9 2 - 3 ) = 163 Hence, the next number in the given sequence is 163.

Question 7

Find the next number in the given number sequence? 101, 98, 93, 86, 75, ?

Accepted Answer

The given number sequence is 101, 98, 93, 86, 75, ? 101 101 - 3 = 98 98 - 5 = 93 93 - 7 = 86 86 - 11 = 75 75 - 13 = 62 Here the series follows a pattern that consecutive subtraction of prime numbers. Hence, the next number in the sequence is 62.

Question 8

Choose the correct alternative that will continue the same pattern and replace 'x' in the series 31,45,35,47,39,x,43,51,47,53

Accepted Answer

The given sequence is a combination of two series 1)31,35,39,43,47 2) 45,47,49,51,53 So,the missing term is 49

Question 9

Find out the wrong term in the series 4,8,15,25,36,54

Accepted Answer

The correct pattern is +4,+7,+10,+13,+16 So, 36 is wrong term and it must be replaced by 25+13=38

Question 10

In the following question, various terms of an alphabet series are given with one or more terms missing as shown by (?). Choose the missing terms out of the given alternatives. CMW, HRB, ?, RBL, WGQ, BLV

Accepted Answer

The letters move five steps forward.

Question 11

In the following question, various terms of an alphabet series are given with one or more terms missing as shown by (?). Choose the missing terms out of the given alternatives. A, B, N, C, D, O, E, F, P, ?, ?, ?

Accepted Answer

The series consists of 2 groups (A, B, C, D, E, F, ?, ?) and (N, O, P, ?). The series is made of two terms of first group followed by one term of second group.

Question 12

Which of the following groups of alphabets should replace the blank spaces so that the group of alphabets, given in bold, follow a logical pattern from the preceding and the following group of alphabets? b w _ y z a, d s t u v _ , _ o p q r e

Accepted Answer

b w x y z a d s t u v c f o p q r e

Question 13

prp qrp prr pqr qrp rpr qqr rpr qpr qrr qpr qpr If every third letter starting from the left is replaced by a number beginning with 1 then which letter/ number will be 16th from the right?

Accepted Answer

New sequence is as follows: pr1 qr2 pr3 pq4 qr5 rp6 qq7 rp8 qp9 qr10 qp11 qp12 16th from the right end is 7

Question 14

CGE, RNP, FJH, OKM, IMK, __

Accepted Answer

Here it can be seen that it is not a continuous series. so take alternative terms. CGE, FJH, IMK and RNP, OKM,__ Between R and O there is a gap of two letters. so the first letter in the answer is L.Proceding like this the answer is LHJ

Question 15

Choose the missing terms in the given series from the four alternatives given below. GMQ, JOT, MQW, ?

Accepted Answer

The first letter moves three steps forward. The second letter moves two steps forward. The third letter moves three steps forward.

Question 16

Find the missing number in the given number series? 625, 625, 600, ?, 475, 875

Accepted Answer

Here the given number series 625, 625, 600, ?, 475, 875 follows a pattern that 625 625 + (0 x 0) = 625 625 - (5 x 5) = 625 - 25 = 600 600 + (10 x 10) = 600 + 100 = 700 700 - (15 x 15) = 700 - 225 = 475 475 + (20 x 20) = 475 + 400 = 875 Hence, the missing number in the given number series is 700.

Question 17

Guess the next number in the given number series? 999, 990, 998, 991, 997, 992, ?

Accepted Answer

The given number series 999, 990, 998, 991, 997, 992, ? It follows a pattern that, 999 999 - 9 = 990 990 + 8 = 998 998 - 7 = 991 991 + 6 = 997 997 - 5 = 992 992 + 4 = 996 Hence, the next number in the given number series is 996.

Question 18

What will come in place of the question marks (?) in the following Number series?8, 14, 26, 44, 68 (?)

Accepted Answer

The pattern is + 6, + 12, + 18, +24 ...........So the missing term is = 68 +30 = 98
