The sequence is a geometric sequence, and the sum of the geometric sequence is 2391484

How to determine the sum?

The sequence is given as:

1,3,9

The above sequence is a geometric sequence, with the following parameters:

  • First term, a =1
  • Common ratio, r = 3
  • Number of terms,  = 14

The sum is calculated using:

[tex]S_n =\frac{a * (r^n - 1)}{r - 1}[/tex]

So, we have:

[tex]S_n =\frac{1 * (3^{14} - 1)}{3 - 1}[/tex]

Evaluate

S14 = 2391484

Hence, the sum of the geometric sequence is 2391484
