Which statements about geometric sequences are correct? Check all that apply. In a geometric sequence, the ratio between each of the consecutive terms is the same, or constant. Multiply the common ratio by the last term to extend a geometric sequence.
The sequence 2, 8, 32, 128, . . . is geometric.
The sequence 5, 10, 15, 20, . . . is geometric.
The sequence 3, 18, 108, 648, . . . is geometric.

the 1st & 3rd sequence is correct

Step-by-step explanation:

R=a2/a1

8/2=4

2*4=8

8*4=32

32*4=128

Same for the other sequence

10/5=2

5*2=10

10*2=20 therefore this is not a geometric

Last is 18/3=6

3*6=18

18*6=108

108*6= 648

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.
