Reiny
F(1) = 1
F(2) = 1
F(n) = F(n1) + F(n2), n > 2, n is an element of N (natural numbers)
so next two numbers .... 89, 144 , 233

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.
