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
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 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
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
Here the series of the form is
53 x 2 - 4 = 106 - 4 = 102
The difference of the two consecutive numbers are 1, 4, 9, 16, 25, 35.
This is clearly ,
Here 35 is wrong, So our wrong number is 91
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
But 28 has been given in problem series.
so 28 is wrong number.
First letter moves 6 steps forward. Second letter moves 6 steps backward.
Clearly, alternatively we add and subtract 10% of a term to obtain the next term of the series.
Thus, 10000 + (10% of 10000)= 11000;
11000 - (10% of 11000) = 9900;
9900 + (10% of 9900) = 10890;
10890 - (10% of 10890) = 9801.
9801 + (10% of 9801) = 9801+980 = 10781.
So, missing term = 10890- (10% of 10890)= 9801.
The given sequence is a combination of two series:
i)0, 3, 8, 15, 24, 35
ii)2, 5, 10, 18, 26
The pattern in both i, ii is +3, +5, +7, . . . .
So, in ii) 18 is wrong and must be replaced by (10 + 7) = 17
