so now they have fibonacci sequence like this
1+3+8+21+55+144 =
it's supposed to be 1+2+3+5+8+13+21+34+55+89+144
u know what im saying?

There is a trick. Try adding a few and see what you get.
1 + 3 = 4, what's special about 4?
1 + 3 + 8 = 12, what's special about 12?
1 + 3 + 8 + 21 = 33, what's special about 33?
1 + 3 + 8 + 21 + 55 = 88, what's special about 88?
There's also a trick for the "even" Fibonacci's.
1 + 3 = 4, what's special about 4?
1 + 3 + 8 = 12, what's special about 12?
1 + 3 + 8 + 21 = 33, what's special about 33?

Irrelevant since 2007.

To further the hint, consider the recursive relationship of Fibbi's
Latex doesn't seem to be working I typed F_{n+2}=F_{n+1}+F_n and i got lots of errors...

Using [unparseable or potentially dangerous latex formula]
[unparseable or potentially dangerous latex formula][unparseable or potentially dangerous latex formula]
Which from your previous formula for summing Fibonacci numbers, says
[unparseable or potentially dangerous latex formula]
So, you should take the next fibonacci number and subtract [unparseable or potentially dangerous latex formula]. You can find the next fibonacci number, [unparseable or potentially dangerous latex formula] by noticing [unparseable or potentially dangerous latex formula] or if you subtract, [unparseable or potentially dangerous latex formula]
[unparseable or potentially dangerous latex formula].
So, to get your answer, double the last number, subtract the number before it, then subtract [unparseable or potentially dangerous latex formula] more.
E.g. [unparseable or potentially dangerous latex formula]

Lol, I came up with your method at practice today.
Our old trick was to get the next one, but I decided doubling minus the one before minus 1 was better.
