    Well for this type of problem, we have to anaylse the series properly..

    Notice the 1st, 2nd and 3rd terms..

    8, 4, 2 ...
    They have a common trend as in:

    8 / 2 = 4
    4 / 2 = 2

    Thus to confirm my analogy, try it on the 4th term:

    4th term = 2/2 = 1

    It's correct. Thus the rule of this sequence: Starting from the first term, the next term is being obtained by dividing the previous term by 2 in order to obtain the next terms.

    Thus, the next few terms will be:

    7th term: 1/4 divided by 2 = 1/8
    8th term: 1/8 divided by 2 = 1/16

    and so on...

    Got it
