Question

How do I write a Recursive Formula for an Arithmetic sequence?

Answer 1

in general, you see how the next term in a sequence relates to the previous one
How do you go from a(n) to a(n+1)?

Answer 2

by \[\frac{ 1 }{ 3 }\]

Answer 3

Essentially write out the relation a(n+1) = f(a(n))

Answer 4

\[a(n+1)=\frac{ 1 }{ 3 }(a(n))\]?
