Question

Please help me i honest to god don't know what I'm doing

Answer 1

`a_1`=1,

`a_n=a_n_-_1(-7)`

Explanation:

I was learning this a few years back, 9th grade I think, it's not really difficult, a tip that I will give you is to search up a video explaining the variables in the formula of both recursive and explicit.

I'm sure that you can do it and do well on your tests, good luck!

Hope this helped! :)
