Let us simplify our given expression.
Let us see which of our given choices matches with our answer.
A.
Upon using distributive property we will get,
Therefore, option A is a correct choice.
B.
Upon using distributive property we will get,
Since this expression is not equivalent to our answer, therefore, option B is not a correct choice.
C.
Upon removing parenthesis we will get,

Therefore, option C is the correct choice.
The next three terms are: 1/6 , 0 and -1/6
Step-by-step explanation:
Given sequence is:
First of all, we have to find the common difference
The common difference is -1/6
We can simply add -1/6 to the previous term to find the next terms so,
Adding -1/6 to 1/3
Hence,
The next three terms are: 1/6 , 0 and -1/6

Answer:
143
Step-by-step explanation:
Substitute n=3 into the problem
6()-2(
) +3-4
Then figure out squared and power by 3
6(27)-2(9)+3-4
Next multiply
162-18+3-4
Finally, add and subtract
144+3=147
147-4=143
