    Answer : Option A

    Explanation :

    The given series is made of two different series:

    First: 455, 465, 485, 515, and

    Second: 445, 435, 415,455

    The sequence in first series is + 10, + 20, + 30, and the sequence in second series: -10, -20. So, the number 455 is wrong as it should be 415 - 30 = 385
