Correct Answer: Granite
Explanation:
Except Granite all other options belong to the group of precious stones.
Correct Answer: 523
Explanation:
Each number is twice the preceding one with 1 added or subtracted alternatively.
So, the next number is (2 x 261 + 1) = 523.
Correct Answer: 2Y4
Explanation:
The digits on either side of the letter in each of the groups 1P6, 2T0, and 1R8 indicate the place value of the letter in the alphabet.
This pattern is not followed by 2Y4.
Correct Answer: 40
Explanation:
The differences between two successive terms from the beginning are 7, 5, 7, 5, 7, 5.
So, 40 is wrong.
Correct Answer: 228
Explanation:
Let the given numbers be A, B, C, D, E, F, G.
Then, A, A x 1 + 1, B x 2 + 2, C x 3 + 3, D x 4 + 4, E x 5 + 5, F x 6 + 6 are the required numbers.
Clearly, 228 is wrong.
Correct Answer: 54
Explanation:
In given Series, all the numbers except 54 are multiples of 5.
Correct Answer: 165
Explanation:
From the beginning, the next term comes by adding prime numbers in a sequence of 2, 3, 5, 7, 9, 11, 13... to its previous term. But 165 will not be in the series as it must be replaced by 166 since 153+13 = 166.
Correct Answer: 9
Explanation:
Terms at odd places are 5, 6, 7, 8 etc. and each term at even place is 16.
So, 9 is wrong.
Correct Answer: 27
Explanation:
In the given series numbers are arranged following the rule,
Therefore, the missing number is 27.
Correct Answer: 16
Explanation:
The given number series is 8, 16, 20, 36, 68
8
8 x 2 - 4 = 12 (NOT 16)
12 x 2 - 4 = 20
20 x 2 - 4 = 36
36 x 2 - 4 = 68
Hence, the odd man in the given series is 16.
