Question

The total number of fungal spores can be found using an infinite geometric series where a1 = 9 and the common ratio is 5. Find the sum of this infinite series that will be the upper limit of the fungal spores.

Answer 1

answer choices:
A) 95
B) The series is divergent
C) 80
D) 25

Answer 2

The series can be summed to infinity only on the condition that the common ratio is less than 1.

Answer 3

so it's divergent?

Answer 4

Answer 5

correct the gp series in convergent when |r|<1

Answer 6

B
