4 answers

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??????????????????
plus I'm in 4th grade
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.
