Number Series MCQ Quiz - Objective Question with Answer for Number Series - Download Free PDF

Given:

Series given is: 3, 13, 31, 58, 91, 111, 

Solution:

The pattern followed here is: x² + (x + 1)

3 = 1² + (1 + 1) = 3

13 = 3² + (3 + 1) = 13

31 = 5² + (5 + 1) = 31

58 = 7² + (7 + 1) = 49 + 8 = 57 ≠ 58, is wrong.

91 = 9² + (9 + 1) = 91

111 = 11² + (11 + 1) = 133

So, "57" is the wrong one in this series.

Hence the correct answer is "57".

 Alternate Method

The pattern followed here is: x2 - (x - 1)

3 = 2² - (2 - 1) = 4 -1 = 3

13 = 4² - (4 - 1) = 16 - 3 = 13

31 = 6² - (6 - 1) = 36 - 5 = 31

58 = 8² - (8 - 1) = 64 - 7 = 57 ≠ 58, is wrong.

91 = 10² - (10 - 1) = 100 - 9 = 91

111 = 12² - (12 - 1) = 144 - 11 = 133
Hence the correct answer is "57".

The given number series: 2, 7, 14, 23, ?, 47

The difference between two consecutive numbers is an odd number increasing from left to right as shown below:

Hence, "34" is the missing term in the series.

The logic follows here is:

Thus, 20.25 will be the next number in the series.

Hence, the correct answer is "Option 3".

The logic followed here is,

Hence, the correct answer is "150".

The logic followed here is:

Hence, "Option 2" is the correct answer.

The logic followed here is: 

Addition of the square of the odd number to previous number to get next number in the series.

13 + 1² =13 + 1 = 14

14 + 3² = 14 + 9 = 23

23 + 5² = 23 + 25 = 48 

48 + 7² = 48 + 49 = 97 

97 + 9² = 97 + 81 = 178

178 + 11² = 178 + 121 = 299 

Hence, the correct option is 299

The pattern followed here is:

Hence, '176' is the correct answer.

Can you solve this number series puzzle? 11, 13, 19, 49, 109, 239, ? – Find the logic and the missing number with a simple and clear explanation

The pattern followed here is:

Hence, 449 is the correct answer.

The number from among the given options that can replace the question mark (?) in the following series is as shown below :-

Hence, the correct answer is "262".

Alternate Method 
Hence, the correct answer is "262".

The pattern followed here is:

6 × 2  + 4 = 16

16 × 2 - 3 = 29

29 × 2 + 4 = 62

62 × 2 - 3 = 121 

121 × 2 + 4 = 246

The logic followed here is :-

Hence, the correct answer is "113".

The logic follows here:

Hence, the correct answer is "1788".

The pattern followed here is as follows:

Hence, value of '?' is 140.

The pattern followed here is as below:-

Hence, 15 + 16 = 31 is the correct answer.

The pattern followed here is:

(Previous number × 3) + (previous number – 2) = next number

Given: 5, 18, 70, 278, ?

1^st number → 5

2^nd number → (5 × 3) + (5 - 2) = 15 + 3 = 18

3^rd number → (18 × 3) + (18 - 2) = 54 + 16 = 70

4^th number → (70 × 3) + (70 - 2) = 210 + 68 = 278

5^th number → (278 × 3) + (278 - 2) = 834 + 276 = 1110

Hence, ''1110" is the correct answer.

Alternate MethodThe logic followed here is:

The Previous number × 4 - 2 = next number.

5, 18, 70, 278, ?

5 × 4 - 2 = 18

18 × 4 - 2 = 70

70 × 4 - 2 = 278

278 × 4 - 2 = 1110

Hence, the correct answer is "1110".
