In each step, the shapes move to the next box in the clockwise direction.

The colour of the boxes is constant.

So, the figure that will come next in the above pattern is :

Answer: Option B. ->  VMTORHS
:
B
According to the given code of secret language,  
$E\to VN\to MG\to TL\to OI\to RS\to HH\to S\therefore Originalmessage-ENGLISHSecretmessage-VMTORHS$

Answer: Option B. -> 37
:
B

In the above figures, we observe that the sum of the numbers diagonally opposite to each other is equal to the number in the circle.

For example, in the first square 10 + 19 = 18 + 11 = 29

So, the number in place of '?' = 14 + 23 = 15 + 22 = 37

Answer: Option D. -> 64
:
D

The sequence follows:
144, 121, 100, 81, ____
$144=12\times 12121=11\times 11100=10\times 1081=9\times 9$
We can see that each term of the sequence is the square of a number. It means a number is multiplied by itself.
Also, the number multiplied with itself in the following term is one less than the previous term.
So, the next term in the sequence is the square of 8, which is
$8\times 8=64$

Answer: Option B. ->  22 B
:
B

The above sequence can be split into two sequences, one having numbers and another having alphabets:

The number pattern is as follows:

So, the next term in the above pattern is 22.

The sequence of the alphabets is:

F, E, D, C

We observe that the alphabets are in reverse alphabetical order.

So the next term in the sequence of alphabets is B.

So, the next term in the sequence is 22 B.

So, the sequence becomes 12 F, 13 E, 15 D, 18 C, 22 B.

Answer: Option B. -> E25V
:
B
The terms of the above sequence can be split into three sequences.
The first alphabet of each term: A, B, C, D
These are in alphabetical order, so the next term will have the alphabet E.
The sequence of numbers: 5, 10, 15, 20
These numbers are the multiples of 5, so the number in the number in the next term is 25.
The second alphabet of each term: Z, Y, X, W
These terms are in reverse alphabetical order, so the second alphabet in the next term is V.
Therefore, the next term in the sequence is E25V.

Answer: Option A. -> 82
:
A
The sequence follows 2, 5, 10, 17, 26, 37, 50, 65, ___.
We can observe,
5 - 2 = 3
10 - 5 = 5
17 - 10 = 7
26 - 17 = 9
37 - 26 = 11
50 - 37 = 13
65 - 50 = 15
If we find the difference between the differences between any two consecutive terms, it is equal to 2.
So, the next term in the sequence will be (15 + 2) or 17 more than the last given term.
That is,
 65 + 17 = 82

Answer: Option C. -> 3140924
:
C

The pattern given is 3140624, 3140724, 3140824, _______

Let us calculate the difference between two consecutive terms. 

3140724 - 3140624 = 100

3140824 - 3140724 = 100

 

We observe that each term in the sequence is 100 more than the previous term.

So, the next term in the sequence = 3140824 + 100 = 3140924

 

Answer: Option B. -> 49, 64
:
B

The terms in the sequence are:

$1=1\times 14=2\times 29=3\times 316=4\times 425=5\times 536=6\times 6$

We observe that the n${}^{th}$ term in the sequence is n $\times$ n.

So, the 7th term of the sequence = 7 $\times$ 7 = 49

The 8th term in the sequence = 8 $\times$ 8 = 64

So, the next two terms in the sequence are 49, 64.

As we can observe in the above pattern, the four dots are rotated in clockwise direction in each step.

So the figure that comes next in the pattern will be:
