We are given the following two points.
Let us find the distance between these two points.
Recall that the distance formula is given by
A geometric sequence is defined by a starting point, , and a common ratio
The first term is , and you get every next term by multiplying the previous one by r.
So, our terms are
We can see that when we pass from to
the number gets halved (
)
This implies that the common ratio is
So, the table becomes
So, we can derive the starting point from either or
:
The sequence is thus
And the recursive formula is
