Answer:
20-2(n-1)
Step-by-step explanation:
The general term (or the nth term) of this sequence is [20-2(n-1)].
Verification:
1st term = 20-2(1-1) = 20-2(0) = 20-0 = 20
2nd term = 20-2(2-1) = 20-2(1) = 20-2 = 18
3rd term = 20-2(3-1) = 20-2(2) = 20-4 = 16
4th term = 20-2(4-1) = 20-2(3) = 20-6 = 14
7 stamps* ($2.20/ 5 stamps)= $3.08.
(Note that the unit cancels out so you get the answer)
The final answer is $3.08~
