Answer
(with step-by-step explanation):
[Find first the value of the 5th term.]
an = a1(r)^n-1
A5 = 2(3)^5-1 = 2(3)⁴ = 2(81) = 162
[Use the formula in finding sum of terms in Geometric Sequence]
Sn = [a1 - an(r)] / 1 - r
[Substitute the given values]
S5 = [2 - 162(3)] / 1 - 3
= 2-486 / -2 = -484/-2 = 242
• Therefore, the answer is Letter B, 242.
