Answer:
A
Step-by-step explanation:
A recursive formula allows the term in a sequence to be obtained from the previous term.
To find any term in the sequence multiply the previous term by the common ratio r
r = - 6 ÷ 2 = 18 ÷ - 6 = - 3
Thus the 9 th term can be found using
f(9) = f(8) × - 3 = - 3f(8) → A

Givens
Petri Dish A sees a double ever 10 minutes
Petri Dish B sees a double ever 6 minutes
Consequences
A doubles 60 / 10 = 6 times.
B doubles 60 / 6 = 10 times.
Solution
If you work best with numbers then suppose there are 100 bacteria in both dishes at the beginning
A = 100 * 2^6
B = 100 * 2^10
A will have 100 * 64 = 6400 bacteria growing inside A
B will have 100 * 1024 = 102400 bacteria growing inside B
B/A = 102400 / 6400 = 16
There are 16 times as many in B than in A. <<<< Answer
