  3. it can be this way.....

    3 7 10 11 12 17 ??
    +4 +3 +1 +1 +5 ?

    4-3=1
    1-x=5
    so x=-4
    so the next number is 13

  6. add alternative numbers and subtract with one will give the 2nd value of the series..
    3,7,10,11,12,17
    3+10-1=12
    7+11-1=17
    so the next number will be 10+12-1=21
