  • MATH -

    F(1) = 1
    F(2) = 1
    F(n) = F(n-1) + F(n-2), n > 2, n is an element of N (natural numbers)

    so next two numbers .... 89, 144 , 233

    the rule??????????????????

  • MATH -

    plus I'm in 4th grade

  • MATH -

    ok, in words ...
    "to get the next number, add up the two previous ones"

    e.g. 5+8 = 13
    21+34 = 55
    etc.

    BTW, to type " the rule ??????????? " is not the most polite way for a 4th grade to ask for help.
