Which of the following represents a geometric sequence?
a. 1/4, 1/4, 1/4, 1/4
b. 1/4, 1/5, 1/6, 1/7
c. 1/4, 1, -4, 16
d. 1/4, -4, 1/4, -4

 Option 'A' is correct.

Step-by-step explanation:

Since we need to find the geometric sequence ,

For this we find the " common ratio" :

On the other hand, in options 'B' , 'C' and 'D' , there is no common ratio,

Hence, Option 'A' is correct.

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

hope this ! : 3
