Question

I need to check my answer please! I chose B.

Generate the first 5 terms of this sequence:

f(1) = 0 and f(2) = 1, f(n) = f(n - 1) + f(n - 2), for n > 2.

0, -1, 1, 0, 2

0, 1, 1, 2, 3

0, 1, 2, 2, 3

0, 1, 1, 2, 2

Answer 2

yeah generate the first 5 terms... where exactly are you stuck ?

Answer 3

Notice that you're already given the first two terms :
```
f(1) = 0
f(2) = 1
```

Answer 4

im not stuck i just want to make sure im correct

Answer 5

So the sequence stars like below :

0, 1, ...

Answer 6

and i know it's not A

Answer 7

thats a very good start !

Answer 8

lets generate the third term

Answer 9

looks we're given a formula for generating terms ?

Answer 10

` f(n) = f(n - 1) + f(n - 2)`

plugin n = 3, you wil get the 3rd term :

f(3) = f(3-1) + f(3-2)
= f(2) + f(1)
= ?

Answer 11

the thing is that i dont really know how to add f(2) + f(1) because the lesson did not really explain everything to me... i read it over again like 3 times.. :(

Answer 12

f(2) = second term
f(1) = first term

Answer 13

just add the first and second terms to get the third term :)

Answer 14

1

Answer 15

Perfect !
f(3) = third term = 1

Answer 16

So far the sequence is :

0, 1, 1,...

Answer 17
