Answer:
28 - 4n
Step-by-step explanation:
What is the recursive formula for this sequence? 24,20,16,12
the sequence first term is 24
a= 24
Common difference (d) = T2 - T1 = T3 - T2
d = 20-24 = 16 -20
d = -4
Formula for nth term
Tn = a + (n-1)d
Tn = 24 + (n -1)-4
Tn = 24 -4n + 4
Tn = 28 - 4n
= 28 - 4n

Answer:
It would take 5.5 months for the two cable companies to cost the same.
Step-by-step explanation:
50x + 100 = 60x + 45
-45 -45
50x + 55 = 60x
-50x -50x
55 = 10x
/10 /10
x = 5.5
