the numbers below are Fibonacci numbers.
1,1,2,3,5,8,13,21,34,55,...
write a rule for the pattern. what are the next three numbers?

MATH 
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 
MATH 
julian,
the rule??????????????????

MATH 
julian,
plus I'm in 4th grade

MATH 
Reiny,
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. 
MATH 
julian,
sorry
