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:

Answer:
35
Step-by-step explanation:
Double the first equation and get 2x + 2y = 300 (1). Call the second equation 2x + 5y = 405 (2). Calculate (2) - (1) to get 3y = 105, so y = 35.
