Answer:
The explicit formula for a given geometric sequence is of the form
Step-by-step explanation:
Given sequence is 
Let 
To find the common ratio r:
Therefore r=-3
Therefore r=-3
Therefore common ratio is -3
Therefore given sequence is geometric sequence.
The explicit formula for a geometric sequence is 
, where common ratio is r.
From given sequence we are having r=-3
Therefore the explicit formula for a given geometric sequence is of the form 
Answer:

Step-by-step explanation:
15/2=7.5
Answer would be B. Sorry if my handwriting is messy or if I didn’t explain enough
Answer
The equation simplified is: r=x+1
Answer:
Variation equation: y = k/√x
constant of variation: 200
Variation Equation by plugging the value of k: y = 200/√x
Step-by-step explanation:
If y varies inversely with the SQUARE ROOT of x, then;
y = k/√x
If x = 4, y = 100.
100 = k/√4
100 = k/2
200 = k
k = 200
Substitute into the expression
y = k/√x
y = 200/√x
