Answer:
180 is the answer you multiple 6 times 30
This is a linear equation. since there is no exponent on the x, x is just to the power of 1. anything to the power of 1 is considered a linear equation. you could also do the vertical line test and find that when you plug any number in for x, none of the final answers will repeat each other. i hope this makes sense and that this helps!!
The explicit formula of the sequence is given by a_n = -4n(n-1).
We have to find the first five terms of the sequence.
The first term:

The second term:

The third sum:

The fourth term:

The fifth term:

Thus, option D is correct.
Since you don't have b and c as a answer choice cause those are the answer
Photomath is good for this type of thing
