It would be to little because it would only be 30 cents
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

Answer:
its 0.45
Step-by-step explanation:
Given :-
To Find :-
- The expression that is equivalent to one of the choices given .
Solution :-
As we know that ,
→ (-) × (-) = (+)
→ (-) × (+) = (-)
→ (+) × (-) = (-)
→ (+) × (+) = (+)
On using these open the brackets ,
→ -1/3 - 1( -4 + 1/6 )
→ -1/3 - 1(-4) + -1(+1/6)
→ -1/3 (-)(-)(1* 4) (+)(-) (1*1/6)
On using now above stated rules ,
→ -1/3 +4 -1/6
Somewhat rearrange ,
→ 4 -1/3 -1/6
Take (-) as common,
→ 4 - (1/3 +1/6)
<u>Hence Option </u><u>(</u><u>d)</u><u> </u><u>&</u><u> </u><u>(f) </u><u>are</u><u> correct .</u>
I hope this helps.
