The logic followed here is,

Hence, the correct answer is "19".

The given number series: 2, 20, 74, 110, ?

The difference between any two consecutive numbers is a multiple of 9.

Thus, the difference between the next number and 110 should be a multiple of 9.

1) 152 - 110 = 42

2) 182 - 110 = 72

3) 190 - 110 = 80

4) 210 - 110 = 100

Thus, the difference between 182 and 110 is a multiple of 9.

Hence, "182" will be the next term in the series.

The logic here is as follows:

Hence, the correct answer is "10".

The pattern followed is

Hence, 18 is the correct answer.

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 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 follows here:

Hence, the correct answer is "1788".

The logic followed here is :-

Hence, the correct answer is "113".

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".
