Consider the sequence 2,6,18,54,...
Let n = the term number in the sequence.
Let A(n) = the value of the nth term of the sequence.
What is the comon ratio of the sequence.?
Complete each statement.
a. A(1) = 2 = 2 x 3^?
b. A(2) = 6 = 2 x 3 = 2 x 3^?
c. A(3) = 18 = 2 x 3 x 3 = 2 x 3^?
d. A(4) = 54 = 2 x 3 x 3 x 3 = 2 x 3^?
Thanks! (: Medals will be given lol.
