It could be 25.01, 10000, etc
The explicit formula is an= 4.2* 
.
The correct option is (b)
<h3>What is explicit formula?</h3>
The explicit formula for a geometric sequence is of the form an = a1r-1, where r is the common ratio.
Given sequence: {4.2, 3.57, 3.0345, 2.5793, …}
General formula 
an=4.2* 
an= 4.2*
Hence, an= 4.2*

Answer: 20 questions
Step-by-step explanation:
From the question, Noah is taking an online survey and after answering 16 questions, he gets a message that he has completed 80% of the survey.
To get the total number of questions in the survey goes thus:
Let the total number of questions be y.
80% of y = 16
80/100 × y = 16
0.8 × y = 16
0.8y = 16
Divide both side by 0.8
y = 16/0.8
y = 20
The survey has 20 questions.
Answer:
y=-6
Step-by-step explanation:
1. plug in the values, it will be y=4/3(-6) + 2
2. simplify
y=-24/3 + 2
y=-8+2
y=-6

Answer:
B
Step-by-step explanation:
Notice that the y intercept is 125 and that each time week it goes down by 25 meaning the slope is equal to -25
this means our equation is
-25x+125=y which is the same as b
