Pattern is:

3+13=16

16+13=29

29+13=42

42+13=55

Hence, option B is the correct answer.

Hence, option B is the correct answer.

The pattern is:

Hence, option B is the correct answer.

The series is following the pattern shown below: -

2807 – 7 = 2800/2 = 1400

1400 – 6 = 1394/2 = 697

697 – 5 = 692/2 = 346 (i.e. option D)

346 – 4 = 342/2 = 171

171 – 3 = 168/2 = 84.

Hence, option D is the correct answer.

The logic followed here is that the letters in next cluster will be -10 from the positional value of letters in the previous cluster.

Z-10=P

W-10=M

T-10=j

Hence, option A is the correct answer.

The Logic is explained below

8+10=18

18+8=26

26+6=32

32+4=36

36+2=38

Hence, option C is the correct answer.

The logic followed here is that letters on odd places follow +2 and letters on even places follow -2 pattern

C+2=E

W-2=U

E+2=G

Hence, option A is the correct answer.

m-2=k k-2=i i-2=g

n+2=p p+2=r r+2=t

L-2=j j-2=h h-2=f

Hence, option A is the correct answer.

pattern is:

Hence, option C is the correct answer.

pattern is:

40*1=40

40+2=42

42*3=126

126+4=130

130*5=650

Hence, option D is the correct answer.
