Answer:
Step-by-step explanation:
(-1/9) /(1/3) = (1/3)/(-1) = -1/3....the common ratio of geometric sequence
the recursive rule is :
the nth term is : An =A1 × r^(n-1)
r : the common ratio
A1 ; the first term
r = -1/3 and A1 = 3
An =3 ×(-1/3)^(n-1)
Do u add or what I don’t understand but 257+97=345
Answer:
The answer is B
Step-by-step explanation:
You add up all the numbers which should be 600 and divide by the total amount numbers used.
600/15=40.
∴
=2796202.5
Step-by-step explanation:
First term(a) = 
common ratio(r) =
=4
n= 12
=2796202.5
∴ =2796202.5
