Write the explicit formula for the geometric sequence.

• a_n = 2(100)^n-1
• a_n = 100(2)^n-1
• a_n = 100(1/2)^n-1
• a_n = (1/2)(100)^n-1

30 bacteria begin to double each hour. Write a NOW-NEXT rule to model this situation.

• NEXT = NOW x 2, starting at 30

• NEXT = NOW + 2, starting at 30

• NEXT = NOW X 25, starting at 2

• NEXT = NOW + 25, starting at 2
