a sequence is given by the recursive definition: a (sub1)=7 and a (sub n)=a(sub n-1) (2)^n

state the fourth term of this sequence.  I am expected to show how I arrived at my answer.

Well this is several years old, but I need help!! Everywhere on the internet is step by step on how to solve this a(sub n-1) etc. My book has a question a(sub n+1) and I can not find a single video or explanation that includes the +1. My instructor says it is the same. But it is not. My question is a(sub n+1) = 3a (sub 1) +5.
