Melody

and the 3rd one

T1 = 1

T2 = 8

T3 = 27

T4 = 64

T5 = 125

These are just cubic numbers.  Can you do it yourself now?

The second sequence is just as easy.  

I just takes practice, you will get the hang of these.  

Hi Juriemagic,

It is good to see you again.  

T1 = 1

T2 = 1

T3 = 2

T4 = 3

T5 = 5

This is the fibonacci sequence.

I actually do not know how to express the nth term of this sequence in a nice neat way

Obviously   

\(T_1=1\\ T_2=1\\ \text{Where n >2 and n is an integer}\\ T_n=T_{n-1}-T_{n-2}\)

I suspect you need somthing easier to use than that.  Am I right or is that all you want?

Come on guest, that is a bit harsh BUT nyx, you must not plagarize. If you want to copy something you must site your source.

And honestly,  you cannot tell me that you read all that or that you had any good reason to think it could be helpful.

Hi CalculatorUser,

I am really pleased that this forum has enabled you to become hooked on maths. 

If a place like this had existed when I was in High School I would have become totally addicted to it.

Not much has changed for me I guess. 

Still,  I can see that for you it could sometimes be a distraction that you should control.

I am sure you will drop in quite regularly and that will be good all ways around   

Thanks asinus and CPhill,

I was wondering about this one.  

I think the 'they' Tom is referring to are the other kids in the class. 

Wonderman has said enough times that they use this site to bypass the rules of their courses.

Your question is incomplete.
