Thread: general term

Find the general term of this sequence ,

0 , 5 , 6 , 11 , ...

i can see the pattern +5 , +1 , +5 , ...

So i hv this idea ..



where


, where r=2
, where r=3

And so on ..



I am not sure how to continue .. Am i on the right track . Thanks !

Maybe a better way might be to add the amount 3 - 2*(-1)^n at the n-th step...?
