Question

Which best describes the relationship between the successive terms in the sequence shown?

Answer 1

Answer:

• (C)The common ratio is –2.0

Step-by-step explanation:

Given sequence:

• 2.4, –4.8, 9.6, –19.2

This is not AP as the difference in terms is not common

This is GP with the common ratio of -2 as:

• -19.2/9.6 = 9.6/ -4/8 = -4.8/2.4 = -2

Correct choice is (C)
