Question

Determine whether the following sequence is arithmetic, geometric, or neither.

Answer 1

Answer:

B

Step-by-step explanation:

A geometric sequence has a common ratio r between consecutive terms

r = $\frac{a_{2} }{a_{1} }$ = $\frac{a_{3} }{a_{2} }$ = ...

$\frac{-14}{-7}$ = 2

$\frac{-28}{-14}$ = 2

$\frac{-56}{-28}$ = 2

There is a common ratio of 2 between consecutive terms.

Hence sequence is geometric → B
