A 3
B t = -7n +39
C 51.571
It is declining!
32 to 25 decreases by 7
25 to 18 decreases by 7
18 to 11 decreses by 7
The sequence is linear!
39 is the 0th term and our numbers are decreasing by 7 each term.
t = -7n +39 is our equation
a) -7(6) + 39
-49 + 39
3
b) to find nth term replace the term with n in this equation:
t = -7n +39
c) -332 = -7n +39
Subtract 39 from both sides!
-361 = -7n
Divide both sides by -7!
n = 51.571
