    Answer : Option A

    Explanation :

    First Number = 1 *2 *3 = 6
    Second Number = 2*3*4 = 24
    Third Number = 3*4*5 = 60
    Fourth Number = 4*5*6 = 120
    Fifth Number = 5*6*7 = 210
    Sixth Number = 6*7*8 = 336.

    Alternatively,

    2*2*2-2=6
    3*3*3-3=24
    4*4*4-4=60
    5*5*5-5=120
    6*6*6-6=210
    7*7*7-7=336.
