Let be the coordinates of the points A and B and
be the coordinates of the point O that divides the segment AB in ratio 2:3.
Consider vectors
These vectors are collinear and
Then
This means that
Thus,
Answer:
Answer: The correct option is 1, i.e., .
Explanation:
The geometric sequence is in the form of,
Where, a is the first term of the sequence and r is the common ratio of the sequence.
It means the term of the sequence is defined as,
So the the term of the sequence is defined as,
It means the geometric sequence is in the form of,
Where, r be any constant.
From the options only is in the form of
with common ratio
.
Therefore, the function can be used to model the graphed geometric sequence is .
