1,2,3 isn't the first three numbers in the Fibonacci Sequence. Neither is 1,1,2 really, but it's closer than 1,2,3!!

Extend function is not known to my RStudio / RGui. An error to that effect is returned.

I saw 1,1,2 and guessed that as I don't know Python.

Interesting question, thanks Steve
Haven't used Python in quite a few years....

Depends on whether you want to start with F_0 or F_1...

"By definition, the first two numbers in the Fibonacci sequence are either 1 and 1, or 0 and 1, depending on the chosen starting point of the sequence, and each subsequent number is the sum of the previous two."
https://en.wikipedia.org/wiki/Fibonacci_number
If it's on wikipedia, it has to be right!

I guess it depends on who gets to define what the Fibonacci sequence is.
OEIS (https://oeis.org/search?q=Fibonacci&language=english&go=Search) has it start with (0,1[,1]), but the original text has it start with (1,2 [,3]):
"You can indeed see in the margin how we operated, namely that we added the first number to the second, namely the 1 to the 2..." (English translation quote from https://www.math.utah.edu/~beebe/software/java/fibonacci/liber-abaci.html )

This isn't an R question. It's a Python question.

1,2,3 was a typo. It should have been 1, 1, 2 for all answers to make things consistent. Points awarded back.
