Answer 8

oh i did something wrong?

Answer 9

We don't need 2nd 3rd and 4th term to find the fifth...

\(\Large\color{blue}{ t_n=12-2n}\)
is the formula for any term in a sequence, as I can see, so plug in t=5.

Answer 10

you did it right at first, but I am not sure why you found the 1st and 2nd terms after that...

Answer 11

the slope, or the difference, is -2.
