Thanks, for your help Mark! Syd

That equation you presented was correct I did not know how to type it out properly. I see so a_4 = 2*a_3 - 1 = 2(?) - 1 a_5 = 2*a_4 - 1 = 2(?) - 1 a_4 = 2*a_3 -1 = 2(5) - 1 = 9 a_5 = 2* a_4-1 = 2(9) -1 = 17 Is that correct?

Homework Statement a 1= 2, a k+1, 2ak-1 Homework Equations What is the 5th term The Attempt at a Solution a1= 2 a2=2(2)-1= 3 a3=2(3)-1=5 a4=2(4)-1=7 a5=2(5)-1=9 5th term =9?

Thank you all for your help in explaining this, I appreciate it greatly.

F(n) = 2+4+6=...+2n I know the expression that represents the given function is F(n) = n(n+1), my question is F(n) = 3+5+7...2n the same F(n) = n(n+1)< if not can anyone expain? Thanks

yes thanks!

Thanks I got it and I really appreciate your help!
