Answer:
Step-by-step explanation:
The explicit formula for a geometric sequence with first term a1 and common ratio r is ...
In this problem, you are given a1=625 and r=0.2. Filling in those values gives the explicit formula ...
You can either evaluate this function for values of n = 1 through 5, or you can multiply each term by the common ratio to get the next.
a1 = 625
a2 = 625·0.2 = 125
a3 = 125·0.2 = 25
a4 = 25·0.2 = 5
a5 = 5·0.2 = 1
1st , 3rd and last option is correct
The answer to your question is the last one.
Answer:
2)8%
3)=
$
26.46
4)multiply $1.50 and 60%, which will give you 0.9. now multiply $1.50 and 0.9 and that'll give you$1.35. lastly, add $1.50 and $1.35 and that'll give you the answer which is $2.85.
5)15 % of $1580 is $237
6)25%
