20 plz ! which sequence is modeled by the graph below? coordinate plane showing the points 1, 6; 2, 0.6; and 3, 0.06 a) an = 6(−10)n − 1 b) an = 0.6(10)n − 1 c) an = 6(one tenth)n − 1 d) an = one tenth(6)n − 1

option c   is correct

step-by-step explanation:

we will find what type of   sequence is the order of the coordinates:

, and

common difference states that the difference between two numbers in an arithmetic sequence.

then;

and

since, the common differences are not equal;

hence, the sequence is not arithmetic sequence.

geometric sequence states that a sequence of numbers that follows a pattern were the next term is found by multiplying by a constant called the common ratio

now, find the common ratio;

and

therefore, the common ratio is .

this implies that the sequence is geometric sequence.

now, the general form for a geometric series:

where r is the common ratio and is the initial value.              

since the common ratio of the geometric sequence is r =  

now, substitute the value of r and   in [1]; we get

therefore, the given sequence is modeled by the graph is geometric sequence

i.e,
