A1 = 4
a2 = 5a1 = 5 x 4 = 20
a3 = 5a2 = 5 x 20 = 100
a4 = 5a3 = 5 x 100 = 500
a5 = 5a4 = 5 x 500 = 2,500
Tn = ar^(n-1); where a = 4, r = 5
Tn = 4(5)^(n-1) = 4/5 (5)^n
Explicit formular is Tn = 4/5 (5)^n
Recursive formular is
1/5(25-5a)=4-a
⇔5-a=4-a

Answer:
I think its $6894.21
Step-by-step explanation:
compound interest formula: A= P(1+ r/n)^nt
A= 5000(1+ 0.055/1)^1(6)
A= 6894.21403
A= $6894.21
