hmm, because I have shown through the inductive process that 5^k+1 -1 is divisible by 4, and in the base case i took care of the n = 0 because it's not just positive integers, but all natural numbers.
Should it have been therefore 5^k+1 -1 is a multiple of 4.. from the inductive process i was...
Okay i can label them,
So, for the last line i should not state "therefore" i can erase that.
It just seemed like i should have a therefore, after all the steps in conclusion
How should i phrase it then?
Okay got it! i found a few other mistakes i think.
Does this look good?:

Anything else?
Thank you so much for helping by the way :)
Thank you for the help!
1 thing, I am confused on the "base case" i understand it supposed to be "easy" and simple, do i just say n = 0? is that it?
How do i write it?
