Answer:
f(n) = 2 * f(n - 1) + 1
Step-by-step explanation:
First, notice that the difference between each neighboring term is different, so it is not linear, so we can rule out A and B. Now, it's all about finding a pattern. Eventually, through guess and check, you will get 2 * f(n - 1) + 1.
Perhaps there was a typo in C? Idk!!
Answer:
x = 4
Step-by-step explanation:
a = i-2j
b = 2i-xj
1 = k•2
-2 = k•(-x)
=> 1/2 = k
=> (-2)/(-x) = k
=> 1/2 = (-2)/(-x) => 1/2 = 2/x => x = 4
The answer is B. He is incorrect because he should have only 5 factors of 3.
