Find the next number in the given series 0.25, 8, 128, 1024, ?

Correct Answer: 38

Explanation:

The given series is 15, 19, 27, 38, 55, 75

15

15 + 4 = 19

19 + 8 = 27

27 + 12 = 39

39 + 16 = 55

55 + 20 = 75

 

Hence, the odd number in the given series is 38.

Correct Answer: 189

Explanation:

The given number series is 10, 21, 54, 109, 189

The series follows a pattern that

10 + 11 = 21

21 + 33 = 54

54 + 55 = 109

109 + 77 = 186

 

Hence the wrong number in the given number series is 189.

Correct Answer: 289

Explanation:

Here the given number series is 270, 261, 279, 252, 289, 243

270 - 9 = 261

261 + 18 = 279

279 - 27 = 252

252 + 36 = 288 (not equals to 289)

288 - 45 = 243

 

Hence, the odd number in the given number series is 289.

Correct Answer: 81

Explanation:

The series follows the following pattern.

 

4

 

16 =  4 2

 

37 =  1 2 + 6 2

 

58 =  3 2 + 7 2

 

81  ? 5 2 + 8 2.

 

Here every number is based on the digits of previous number. Hence, 81 is the wrong number in the given series.

Correct Answer: 4-15-24

Explanation:

In each term second two numbers are multiples of the first number. But in 4-15-24 15 is not multiple of 4.

Correct Answer: 67

Explanation:

Here the given series 7, 11, 19, 35, ?

follows a pattern that (x 2 - 3) i.e,

7

7 x 2 - 3 = 11

11 x 2 - 3 = 19

19 x 2 - 3 = 35

35 x 2 - 3 = 67

67 x 2 - 3 = 131

 

Hence the next number in the given number series is 67.

Correct Answer: 449

Explanation:

Given number series is 5  19  49  101  181  295 ?

Here the series follows pattern that

5   19   49   101   181   295  ?

  14   30   52    80     114   (difference)

      16  22   28     34 (difference)

         6     6     6  (Common difference)

 

Therefore, the missing number in the series is ? = 295 + 115 + 34 + 6 = 449.

Correct Answer: 88

Explanation:

The given number series 2676, 445, ?, 21,6, 2, 1 follows a pattern that,

From right side,

1

1 x 1 + 1 = 2

2 x 2 + 2 = 6

6 x 3 + 3 = 21

21 x 4 + 4 = 88

88 x 5 + 5 = 445

445 x 6 + 6 = 2676

 

Hence the missing number in the given number series is 88.

Correct Answer: 437

Explanation:

Given number series is 514   470   ?   415   404

 

 

 

Here the pattern it follows is

 

514

 

514 - 44 = 470

 

470 - 33 = 437

 

437 - 22 = 415

 

415 - 11 = 404

 

Hence, the missing number in the given number series is 437.

Correct Answer: 14

Explanation:

Given Number series is :

 

3   4   14   48   576   27648

 

It follows a pattern that,

 

3

 

4

 

4 x 3 = 12   but not 14

 

12 x 4 = 48

 

48 x 12 = 576

 

576 x 48 = 27648

 

 

 

Hence, the odd one in the given Number Series is 14.
