Acertain culture of yeast increases by 50% every three hours. a scientist places 9 grams of the yeast in a culture dish. write the explicit and recursive formulas for the geometric sequence formed by the growth of the yeast

Explicit:  

Recursive:  

Step-by-step explanation:

A certain culture of yeast increases by 50% every three hours

⇒ rate (r) is  

A scientist places 9 grams of the yeast in a culture dish.

⇒ first term of the sequence (a₁) = 9

The explicit rule for a geometric sequence is:

⇒

The recursive rule for a geometric sequence is:

⇒
