()which of the following is a geometric sequence with a common ratio of 2? a. 14, 16, 18, 20, b. 14, 28, 56, 112, c. 87, 85, 83, 81, d. 64, 32, 16, 8,

B.

Step-by-step explanation:

A geometric sequence is a exponential sequence, meaning that it has a common ratio, not a common difference. A common ratio of 2 would be that you multiply the next number by 2.

So

14*2=28

28*2=56

56*2=112

true statements:

a) x + y = y + x   ⇒ commutative property of addition

b) (x * y) * z = x * (y * z) ⇒ associative property of multiplication

d) (x + y) + z = x + (y + z) ⇒ associative property of addition

false statements:

c) x - y = y - x   should be: x - y = - y + x

e) (x - y) - z = x - (y - z) should be: (x - y) - z = x - (y + z)
