Enzo’s profit over the last few months has been falling. in december he made $900, in january his profit was $500, and in march, he lost $300. is the sequence that represents his profit arithmetic? if it is, what is the recursive formula for the sequence?

See explanation

Step-by-step explanation:

Enzo’s profit over the last few months:

Find the difference between given data

Dec - Jan

Jan - Feb

Feb - Mar

If this sequence is arithmetic, then

So, if the profit in February was $100, then this sequence is arithmetic sequence. In this case,

The recursive formula is

a≈380.13mi² would be your answer if the radius was 11 miles

hi there!

not proportional because the 42 does not go into 120 and 3 does not go into 8.

correct proportion: $40/1 ticket.

the reason i say this is because 40/1 is simplified and it evenly goes into 120/3.

hope this : )
