The first term is 7. This is because the sequence has a pattern of increasing by 7. If the first term was 7, the second would be 14, the third would be 21. The 4th would be 28, continue to the 8th term 56.
The answer is a whole number, and it happens to be 1
I would say dynamic is the answer.
Divied 4 by both 180 and 320 because 4 quarters= a dollar
