Question 2 unsaved in the explicit geometric sequence given below, what is the common ratio? an=4⋅3^n−1 question 2 options: 4 0 3 1

Each time the value of n increases by 1, the value of an increases by a factor of 3. The 3rd choice is appropriate.


When an expression like this one is written in plain text, it is appropriate (required) to put parentheses around the exponent that contains an arithmetic operation.
  an = 4·3^(n-1)

If you leave off the parentheses, the expression no longer describes a geometric sequence.
