The answer is 133 dollars cuz 5580-3186 is 2394 and 2394 divided by 18 is 133
The sum of 5 times a number and -8:
5x - 8 = y
The answer to your question is -5
7-4=3
10-7=3
13-10=3
we can see that this is an arithmetic sequence with a difference of 3
the nth term=the first term +(n-1) times the difference
so a(n)=4+3(n-1)
