Answer: D) 135 Explanation: The given number series is 6, 6, 9, 18, 45, ? Here the series follows a pattern that, 6  6 x 1 = 6 6 x 1.5 = 9 9 x 2 = 18 18 x 2.5 = 45 45 x 3 = 135   Hence, the next number in the given number series is 135.

Answer: B) The document required trial by a jury of one's peers. Explanation:

Answer: B) 165 Explanation: The terms of the series are products of two consecutive prime numbers i.e. (2 x 3), (3 x 5), (5 x 7), (7 x 11),..... So, 165 is wrong and must be replaced by (11 x 13) i.e. 143.

Answer: A) 189 स्पष्टीकरण: दी गई संख्या श्रृंखला 10, 21, 54, 109, 189 है श्रृंखला एक पैटर्न का अनुसरण करती है कि 10 + 11 = 21 21 + 33 = 54 54 + 55 = 109 109 + 77 = 186 इसलिए दिए गए में गलत संख्या संख्या श्रृंखला 189 है।

Answer: C) 41 Explanation: The given number series follows the pattern that,   24×0 + 4  = 4     4×1  + 9   = 13   13×2 + 16 = 42   42×3 + 25  = 151   151×4 + 36 =  640   Therefore, the odd number in the given series is 41

Answer: A) 192 Explanation: Given    6   3   3   6   24   ?   Here   6   6 x 0.5 = 3   3 x 1 = 3    3 x 2 = 6   6 x 4 = 24    24 x 8 = 192   The next number in the given series is 192.

Answer: B) 91.12 Explanation: Given number series is 12  9  13.5  30.3  ?  341.7 Here the pattern followed by the series is 12  12 x 0.75 = 9 9 x 1.5 = 13.5 13.5 x 2.25 = 30.3 30.37 x 3 = 91.12 91.12 x 3.75 = 341.71   Hence, the missing number in the sequence is 91.12.

Answer: D) 70 Explanation: Here the given series is 1, 3, 6, 11, 20, 37, ??, and the logic behind the series is 1 x 2 + 1 = 3 3 x 2 + 0 = 6 6 x 2 + (-1) = 11 11 x 2 + (-2) = 20 20 x 2 + (-3) = 37 37 x 2 + (-4) = 70   Hence, the next number in the given series is 70.
