In a geometric progression: a, b, c, d... The common ratio can be obtained using: b/a = c/b = d/c b/a = 112 / 64 = 1.75 c/b = 196 / 112 = 1.75 d/c = 343 / 196 = 1.75 The common ratio = 1.75
The answer is y = -5/7x + 4/7! The first step is to subtract the 5x so it’s on the other side of the equal sign. So now the equation is 7y = -5x + 4. Then divide each of them for 7
