Correct answer only ! the explicit rule for a sequence. what is recursive rule for the sequence?

Step-by-step explanation:

The explicit rule for a geometric sequence is:

The given explicit rule shows that

The recursive rule for a geometric sequence is:

So, the recursive rule is:

typically if you want , you would actually put questions here for us to you. but hey, that's just me. maybe someone will magically answer the questions for you without knowing what they are.

so mark-up is 0.4 multiplied by 180 = 72
