Find the next number in the given number series? 2, 19, 0, 21, ?2, ?

Correct Answer: 450.187

Explanation:

Here the given number series  3, 10.5, 36.75, 128.625, ? follows a pattern that

3

3 x 3.5 = 10.5

10.5 x 3.5 = 36.75

36.75 x 3.5 = 128.625

128.625 x 3.5 = 450.187

 

Hence the next number in the given number series is 450.187.

Correct Answer: NLI

Correct Answer: 364

Explanation:

The given number series is 3, 12, 39, 120, 364

$$\begin{gathered} 3 \\ 3 + 3 2 = 3 + 9 = 12 \\ 12 + 3 3 = 12 + 27 = 39 \\ 39 + 3 4 = 39 + 81 = 120 \\ 120 + 3 5 = 120 + 243 = 363 ( Not 364 ) \end{gathered}$$

Correct Answer: 742

Explanation:

The given number series is 720, 732, 708, 742, 696

 

720

720 + 12 = 732

732 - 24 = 708

708 + 36 = 744 (Not 742)

744 - 48 = 696

 

Hence, the odd man in the given number series is 742.

Correct Answer: 2

Explanation:

Here the given number series is 2 4 27 256 3125 46656

It follows a pattern that,

$$\begin{gathered} 1 1 = 1 \\ 2 2 = 4 \\ 3 3 = 27 \\ 4 4 = 256 \\ 5 5 = 3125 \\ 6 6 = 46656 \end{gathered}$$

 

Hence the wrong number in the given number series is 2 instead of 1.

Correct Answer: 133

Explanation:

Here among the given numbers, 3, 19, 67 are prime numbers. And 133 is not a prime number.

 

Hence, the odd number of the given numbers is 133.

Correct Answer: 86

Explanation:

Here the given number series is 5  11  21  44  ?  175

 

Now the given series follows a pattern, that

 

x2 + 1, x2 - 1, x2 + 2, x2 - 2, x2 + 3, x2 - 3,...

 

Then the missing number is x2 - 2

 

= 44 x 2 - 2 = 88 - 2 = 86

 

Hence, the missing number in the number series is 86.

Correct Answer: 33

Explanation:

The given series follows a pattern that,

+4, +6, +8, +10, +12...

5

5 + 4 = 9

9 + 6 = 15

15 + 8 = 23

23 + 10 = 33

33 + 12 = 45

 

Hence, the missing number in the series is 33.

Correct Answer: VWYZ

Explanation:

K+2 M+1 N-2 L,  P+2 R+1 S-2 Q,   V+1 W+2 Y+1 Z,   J+2 L+1 M-2 K  and  W+2 Y+1 Z-2 X.

Except VWYZ, all the other groups follow similar pattern.

Correct Answer: 70

Explanation:

Here the given series is 1, 3, 6, 11, 20, 37, ??,

and the logic behind the series is

1 x 2 + 1 = 3

3 x 2 + 0 = 6

6 x 2 + (-1) = 11

11 x 2 + (-2) = 20

20 x 2 + (-3) = 37

37 x 2 + (-4) = 70

 

Hence, the next number in the given series is 70.
