What is the common ratio in the geometric sequence 8, 16, 32, 64, 128...?

2

Step-by-step explanation:

To find common ratio, divide a term from it's previous term.

a2/a1 = Common ratio

16/8 = 2

So 2 is answer.

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1
