Which geometric series converges ? i still don’t understand . can someone explain the answer and why !

B

Step-by-step explanation:

A geometric series will only converge if the common ratio r meets the requirement

- 1 < r < 1

The n th term of a geometric sequence is

= a

where a is the first term and r the common ratio

All terms inside the summation are of this form

The only one with - 1 < r < 1 is B where r = = 0.75

the function makes a strait line horizontally with no x intercept but a y intercept at 9.
