Answer 3

Can try my best :)

Answer 4

n=1+2(n-1)^2 solve for the 6th term

Answer 5

So would you just substitute in 6 into the right hand side?

Answer 6

Answer 7

geometric sequence 10 and common ratio =2

Answer 8

Sorry, I don't know. @jdoe0001 Send help?!

Answer 9

\(\bf \textit{looks like }a_{\color{red}{ n}}=a_1\cdot r^{{\color{red}{ r}}-1}\implies a_{\color{red}{ n}}=10\cdot 2^{{\color{red}{ n}}-1}\)

Answer 10

though is easier to post anew, more exposure, so if we dunno someone else may, and we can revise each other
