Answer: A) 278.5 Explanation: The given number series is 35, 36, 55, 111, ? 35 35 x 1 + 1 = 36 36 x 1.5 + 1 = 55 55 x 2 + 1 = 111 111 x 2.5 + 1 = 278.5   Hence, the next number in the given number series is 278.5.

Answer: C) 186 Explanation: The given number series is 3  24  186  1008  5040  20160 Here  the given series follows a pattern that, 3 3 x 8 = 24 24 x 7 = 168 not 186 168 x 6 = 1008 1008 x 5 =  5040 5040 x 4 = 20160   Hence the Odd One in the number series is 186.

Answer: A) 189 Explanation: The given number series is 10, 21, 54, 109, 189 The series follows a pattern that 10 + 11 = 21 21 + 33 = 54 54 + 55 = 109 109 + 77 = 186   Hence the wrong number in the given number series is 189.

Answer: D) 14 Explanation: The given number series is 96, 95, 87, 78, ?  It follows a pattern that, 9696 - 12 = 9595 - 23 = 95 - 8 = 8787 - 32 = 87 - 9 = 7878 - 43 = 78 - 64 = 14   Hence, the next number in the given number series is 14.

Answer: A) 167 Explanation: The given number series is 3, 5, 13, 43, 167 3 3 x 1 + 2 = 5 5 x 2 + 3 = 13 13 x 3 + 4 = 43 43 x 4 + 5 = 177 (not equal to 167)   Hence, the odd number in the given number sequence is 167.

Answer: B) 65 Explanation: The given number series is 50, 51, 47, 56, 40, ?   5050 + 12 = 5151 - 22 = 4747 + 32 = 5656 - 42 = 4040 + 52 = 65   Hence, the next number in the given number series is 65.

Answer: D) 635 Explanation: Given Number series is 18     37     76     155     314     635   follows a pattern that,    18   18 x 2 +1 = 37   37 x 2 +2 = 76   76 x 2 +3 = 155   155 x 2 +4 = 314   314 x 2 +5 = 633 not 635       Hence, the odd man is 635.

Answer: B) 245 Explanation: Given 311   230   294   ?   281   256   311 - (9x9) = 230   230 + (8x8) = 294   294 - (7x7) = 245   245 + (6x6) = 281   281 - (5x5) = 256   Hence, the missing number in the given series is 245.
