    1,4,5,9,13,22,35,48 is a pattern that comes to mind with how its jumping every 2 digits. Don't count on that as the right answer

    1+4=5
    4+5=9
    4+9=13
    9+13=22
    13+22=35
    13+35=48

    Are you saying something like this?

    4-1=3+1(previous no.)=4
    5-4=1+4(previous no.)=5
    9-5=4+5(previous no.)=9
    13-9=4+9(previous no.)=13
    22-13=9+13(previous no.)=22

    But then what will be the next no.?

    Thanks,

    Ron
