1. Wait patiently for a helper to come along.
2. Once someone helps you, say thank you and close the thread with:

5. If you're happy with the help you got here, and the server overall, you can contribute financially as well:

if you plug in values starting from n=1 then you'll notice that the first term is 1 and the rest is 4
so 1,4,4,4,...
another way to think is that the sum of an arithmetic series is quadratic, while this one's is linear, so the general term should be somewhat constant

[visual terrace]

yea :(
Using t_n=S_n - S_(n-1)
t_n=4

so how do I find t_24-t_12=?
Will it be 4-4=0?

why is t_n=first term=1 ?

[wind eagle]

yes 4-4=0
first term 1 cuz S1=t_1

tyyy
