First term = a1 = 7
Common difference = d = 3
The nth term, tn, is given by
tn = a1 + d(n - 1)
tn = 7 + 3(n - 1)
tn = 7 + 3n - 3
tn = 4 + 3n
+128448 10, 7, 4, 1, ...
First term, a1, is 10
Common difference, d, is - 3
The nth term, tn, is given by
tn = a1 + d ( n - 1)
tn = 10 + (-3)(n - 1)
tn = 10 -3n + 3
tn = 13 -3n
+128448 The gym charges new members a $25 application fee. They also charge $10 per month. The table represents the total cost of being a member at the gym for a number of months.
The total cost for belonging n months is given by
Total Cost = Fixed Cost + Variable Cost
Total Cost = 25 + 10n
