Question

3,2,3,6,12,37.5,115.5 which is wrong in this series

Answer 1

12 is wrong in this series . How ? Let see
Series is given, 3 , 2 , 3 , 6 , 12, 37.5 , 115.5
3 × 0.5 + 0.5 = 1.5 + 0.5 = 2
2 × 1 + 1 = 2 + 1 = 3
3 × 1.5 + 1.5 = 4.5 + 1.5 = 6
6 × 2 + 2 = 12 + 2 = 14 [ but here given 12 ]
14 × 2.5 + 2.5 = 35 + 2.5 = 37.5
37.5 × 3 + 3 = 112.5 + 3 = 115.5

Hence, 12 is wrong.
