Question

WILL MARK BRAINLIEST In this geometric sequence, what is the common ratio? 104, -52, 26, -13, ...

Answer 1

Answer:

r = - $\frac{1}{2}$

Step-by-step explanation:

The common ratio r of a geometric sequence is

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

Hence

r = $\frac{-52}{104}$ = $\frac{26}{-52}$ = - $\frac{1}{2}$
