Which of the following solution should be applied to solve for the sum of a geometric sequence with a₁ = 3 and a₅ = 48 with a common ratio (r) of 2?

[tex]a. \: Sn = \: \frac{3(1 - (2)^{5}) }{1 - 2} [/tex]

[tex]b. \: Sn = \frac{48(1 - 3(2) ^{5}) }{1 - 2} [/tex]

[tex]c. \: Sn = \frac{2(1 - 2(3)^{5} )}{1 - 2}[/tex]

[tex]d. \: Sn = \frac{3}{1 - 2}[/tex]
