84x-90 final answer
Step-by-step explanation:
The recursive formula

means that the current element (
) is written in terms of the term immediately before (
).
In order to get
, you have to add 5 to the previous term
. In other words, every term is 5 more than its predecessor.
So, if we want the 8th term, we can keep adding 5 until we get there:
