Find out the wrong number in the given following sequence.
3, 4, 13, 38, 87, 166, 289
The difference between consecutive numbers in the series are the squares of odd numbers.
For example, 4 - 3 = 1
13 - 4 = 9
38 - 13 = 25
87 - 38 = 49
168 - 87 = 81
289 - 168 = 121
Hence the number which is wrong in the series is 166 (it should be 168)
