#1: "In an arithmetic sequence, the difference between one term and the next is constant. In a geometric sequence, each term after the first is found by multiplying the previous one by the common ratio."
#2: A1= 27, A2= 2.7, A3= 0.27, A4= 0.027, A5= 0.0027
#3: An = 6(2/3)^n-1
I have yet to answer #4. Would you happen to know the answer?

Step-by-step explanation:
Multiplying Equation A by (1/3) and adding the result to Equation B will do the trick. Let's actually solve the problem!
Equation A: (5/3)x + 3y = 12
Equation B: 4x - 3y = 8
---------------------------
(5/3 + 12/3)x = 15 Note how this has eliminated the variable
(17/3)x = 15 y.
x = (3/17)(15)
