Answer:

In recursive form, we could write a(n + 1) = 2a(n) with a(1) = 5.

Step-by-step explanation:

If you meant a(n) = 5(2)^(n - 1), then you have a geometric series with first term 5 and common ratio 2.  Each new term is 2 times larger than the previous term.

In recursive form, we could write a(n + 1) = 2a(n) with a(1) = 5.

Example:  If a(1) = 5, the next term, a(1 + 1), or a(2), is 5*2, or 10.
