Answer:
<u>Checkmark:</u>
✓ The sequence is geometric
✓ The recursive formula for the sequence is ;
✓ The explicit formula for the sequence is
Step-by-step explanation:
This is a geometric sequence since there is a common ratio between each term. In this case, multiplying the previous term in the sequence by -3 gives the next term.
r = -3
= -2
Substitute the values in the equation:
This is a explicit formula since the next value depends on the position of n (1, 2, 3 .etc)
The recursive formula would be:
