Recalling Geometric Series Sum Parameters in Logistics Planning

As an operations supervisor for a logistics company, you are analyzing a fuel efficiency plan where the cumulative fuel savings (in gallons) over 15 weeks are modeled by the geometric summation i=1152(3)i\sum_{i=1}^{15} 2(3)^i. To calculate the total fuel savings, you must use the finite geometric series partial-sum formula.

To prepare for this calculation:

  1. State the algebraic formula used to find the sum of a finite geometric series, SnS_n.
  2. Identify the specific numerical values for the first term (a1a_1), the common ratio (rr), and the total number of terms (nn) that must be substituted into this formula for the given summation.
  3. Briefly describe the calculation or step used to determine the first term (a1a_1) from the given summation notation.
