Multiple choice algebra question:
what is the explicit rule for the geometric sequence? 29.7, 9.9, 3.3, 1.1, 

an=29.7(1/3)^n+1

an=29.7(1/3)^n−1

an=29.7(2/3)^n−1

an=29.7(1/3)^n

  an=29.7(1/3)^(n−1)

Step-by-step explanation:

The first and last choices fail on n=1.

The third choice fails on n=2.

The only viable choice is the second one, which describes the sequence perfectly.

hello :

by applying the distributive property :

6 × 4.3 = 6 × ( 4 + 0.3 )

            =   (6 ×   4) + (6 ×   0.3)

            = 24 + 1.8

6 × 4.3 = 25.8
