Which of the following is the rule for the geometric sequence 1, 3, 9, 27, . . .?
Serhud [2]

Answer:

a(n) = 1 \times  {3}^{n - 1}

Step-by-step explanation:

  • We started at 1
  • And it seems that index after index it multiplies by 3
  • The formula for the geometric sequence defined implicitly is a(n) =a(1)r^(n-1)

a(n) = a(1) {r}^{n - 1}  \\  a(n) = 1 \times  {3}^{n - 1}
