Answer 2

Answer: (C) 65,535

Explanation:

Given the sequence {3, 12, 48, 192, ... , 49152} we know the following

• the first term (a₁) = 3
• the common ratio (r) = 4
• the number of terms (n) = 8

Input the information above into the Sum formula:

`S_n=(a_1(1-r^n))/(1-r)\\\\S_8=(3(1-4^8))/(1-4)\\\\.\quad =(3(1-65,536))/(-3)\\\\.\quad =(3(-65,535))/(-3)\\\\.\quad =65,535`
