-547

-1449

given a number of finite in term A sequence infinfely sequence

Answer 1

notice that each number is one-third of its previous number. This is a ______ series.

Answer 2

I saw you post this question 3 times and got the instruction above. It seems you still not know how to step up?
1st number is 648
2nd number is 648/3 = 216
3rd number is 216/3=72
4th number is 72/3= 24
5th number is 24/3 = 8
6th number is 8/3 = 2.67
7th number is 2.67 /3 =0.89
and the general form of this is a_n = a_n-1/3
or if you don't like that form, you can use recursive to construct the form as a_n = 648* (1/3)^n .
if you still not get. don't worry, just make question, I'll be back later

Answer 3

hi friend, I have no idea about yours, I just follow the instruction above. I "translate" it to you . I saw after getting that instruction, you still make the same question in a new post. So I guess so.

Answer 4

Suggestion: if you don't get, make more question, that's it. It seems you are a so shy girl. disappear again when I am talking to you. I'm ok with that, girl!
