Correct Answer: 34
Explanation:
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
Correct Answer: 182
Explanation:
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
Correct Answer: 102
Explanation:
Here the series of the form is
53 x 2 - 4 = 106 - 4 = 102
Correct Answer: 91
Explanation:
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
Correct Answer: 9
Explanation:
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
Correct Answer: N,C
Explanation:
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
Correct Answer: 232
Explanation:
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.
Correct Answer: 28
Explanation:
Here the number follows the given rule
But 28 has been given in problem series.
so 28 is wrong number.
Correct Answer: SH
Explanation:
First letter moves 6 steps forward. Second letter moves 6 steps backward.
Correct Answer: 9801
Explanation:
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.
