Help please
It's difficult to know how to guide you here - can you explain the difficulty you are having? You can see that f(1) and f(2) are correct in all the answers (by comparing with the table) So you must concentrate on how to calculate f(n) when n>2 Look at the formulae in all the answers for whne n=3 for example. See if the formula produces the result which is in the table. If it does then check for n=4,5 &6 Only one of the answers provides the correct results for all values of n
im lost
@MrNood oh and sorry my mom had called me to do someething
look at the table If n=3 tell me what f(n-2) is please?
f(6)
not - that's not it. If n= 3 what does (n-2) =? (So what does f(n-2) = (look at the table)
f(1)
correct - and what is the value of f(1) from the table
1
???
Good - so you can see how to read the values from the table. Now look at the answers. Take the second answer It says that for n>2 then f(n) = f(n -1) + f(n - 2); n > 2 SO using the same method as you did above, right down f(n -1) + f(n - 2) when n=3
f(3)=f(2)+(1);n>2
And what is the value of f(2)+f(1) ?
f(3)
I want the actual numerical values - read them from the table..
what do you mean
Go back to the earlier posts - you told me f(n-2) is f(1) (when n=3) you then looked in the table to see that f(1) is 1 now do the same to find the value of f(2)+f(1)
no
its not the same
The initial posts were just to show you how to read the table. Now - look at the table and find the value of f(2) look at the table and find the value of f(1) Then calculate the value of f(2)+f(1)
f(3)
you are not reading the table. Let's try again What is the value of f(6)?
oh thats what you ment 32
OK - good look at the table and find the value of f(2) look at the table and find the value of f(1) Then calculate the value of f(2)+f(1)
3
OK - that's correct Now - the second answer says f(n) = f(n -1) + f(n - 2) Is this true when n=3? (you have done nearly ALL the work above for this....)
f(3)=f(2)+f(1)
so yes
you wrote down above that f(2)+f(1)=3 that is correct But what is f(3)?
when you add f(1)+f(3) thats f(3)=f(3)
so n is 3
wait im lost what do you mean whats f(3)
I'm really sorry - but you seem to need to revise the meaning of the table and the equations given in the answers. The table lists the values of n (1-6) and the CORRESPONDING values of f(n) I asked you what f(6) was and you correctly answered 32 I asked you what f(3) is and you are confused...
2?
you good im really slow
Tell me how you (correctly) got f(6) = 32
the table
so tell me what f(3) is
2
OK - correct so remember f(3)=2 NOW go back to just now what is (f3-1)+f(3-2)
f(3)
what is the VALUE of (f3-1)+f(3-2) (look at the table...) (you already worked this out)
so its f(2-1)+f(2-2)?
Sorry to have to go now - you really are some way from being able to solve this for yourself. Please take a look at your text book, or speak to your tutor. There are some basic concepts you need to work on before you can answer this. Please don't give up ... good luck
