    13 and 17.

    Each time 4 is being added, so do 9+4=13, then 13+4=17.

    The 5th number is 13 and the 6th number is 17.

    Step-by-step explanation:

    For more difficult question, you have to use this way. the rule for arithmetic sequence is An=a1+d (n-1)

    So all you have to do is replace the things.

    So, you are looking for the 5th spot, the first term is - 3, and the difference is 4, replace the n with the 5.

    A5=-3+4 (5-1)

    5-1 is 4

    4*4 = 16

    A5 = -3+16

    16-3=13

    A5=13

    Do the same for A6, just instead of the "5's" put "6's".

    A6=-3+4 (6-1)

    6-1 + 5

    5*4 = 20

    20-3=17

    A6 = 17
