Look at the following sequence. 128, 320, 800, 2000, . . if it is a geometric sequence, choose the common ratio. if it is not a geometric sequence, choose “not geometric.” 4 not geometric 2.5 1200

It is a geometric sequence en the common ratio is: .

Step-by-step explanation:

1. By definition, a geometric sequence is a sequence in which you obtain a term by multiplying the previous one by a common ratio.

2. The common ratio is obtained by dividing a term by its preceding term.

3. Keeping this on mind, you have:

4. As you can see, the common ratio is

the answer is a

step-by-step explanation:

because if you put 1 in to the square root of x it equals 300.

answer: i think it is (1,-2)
