Total number of cans = N
number of weeks = w
The multiplier is 6.
Therefore the expression must be:
N = 6w
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.
I’m thinking it would be c sorry if it’s incorrect .
