The first numbers increase by 5, 7, 9, 11....
The letters move one step backward.
The last numbers are consecutive odd numbers.

The given sequence is a combination of three series:
i)1st, 4th, 7th terms i.e, 2, 4, 9
ii)2nd, 5th, 8th terms i.e, 3, 6, 12
iii)3rd, 6th, 9th terms i.e, 4, 8, 16
In each one of i, ii, iii, each term is twice the preceding term.
So, 9 is wrong and must be replaced by (4*2) = 8

The difference of the two consecutive numbers are 1, 4, 9, 16, 25, 35. 

This is clearly ,  + 1 2 , + 2 2 , + 3 2 , + 4 2 , + 5 2 , + 6 2 

Here 35 is wrong, So our wrong number is 91

Here the series of the form is  x 2 - 1 , x 2 - 2 , x 2 - 3 , . . .

 53 x 2 - 4 = 106 - 4 = 102

The given series follows a logic that

11 x 12, 12 x 13, 13 x 14, 14 x 15, 15 x 16,...

So the missing number is 13 x 14 = 182

The difference between consecutive numbers of the given series are respectively 5, 7, 9, 11, 13, and 15.

Therefore, 24+11=35 But in your problem it is given as 34.so 34 is wrong number

Z - 2 = X
X - 5 = S
S - 10 = I
I - 17 = R
R - 26 = R
R - 37 = G
G - 50 = I
The series 2, 5, 10, 17, 26, 37, 50 is obtained by the pattern +3, +5, +7, +9, . . . .

The given sequence a combination of two series:
I)Z, W, T, Q, ?      and      II)S, O, K, G, ?

The pattern I is
Z - 3 = W
W - 3 = T
T - 3 = Q
Q - 3 = N

The pattern in II is
S - 4 = O
O - 4 = K
K - 4 = G
G - 4 = C

Here 2nd number = (1st number x 1 )+1

 3rd number = (2nd number x 2 +2) 

4th number = (3rd number x 3 )+3 and so on..

Therefore, 5th number = (4th number x 4) +4 =57 x 4 + 4 =232.

Here the number follows the given rule 

  $$\begin{gathered} 2 3 - 1 , 3 3 - 1 , 4 3 - 1 , 5 3 - 1 , . . . \\ \end{gathered}$$

But 28 has been given in problem series.

so 28 is wrong number.
