Which of the following best describes how the y values are changing over each interval?

x y
1 2
2 4
3 8
4 16
5 32

a) they are increasing by 2 each time.
b) they are increasing by 4 each time.
c) they are being multiplied by 2 each time.
d) they are being multiplied by 4 each time.

C) they are being multiplied by 2 each time.

Step-by-step explanation:

From the given table, we can see that the ratio between values of the y is given by :-

Therefore, the common ratio = 2, which means the y values are increasing by a multiplicative factor of 2.

Therefore, the right option is "The y values are being multiplied by 2 each time."
