Hello!


- On F4 there is indeed a typo, the last term should be $128$.

- For F6 I'm pretty sure that in your case "NO" would not be an appropriate answer: I know YOU can definitely find a pattern to write the "general term". Just make sure to write carefully the first few terms and follow Sophie's advice, she seems to have a good idea over there.


Cheers,

David
