The recursive formula for a geometric sequence is:
.
According to the statement
we have to find that the recursive formula for geometric sequence.
So, For this purpose, we know that the
Geometric Progression (GP) is a type of sequence where each succeeding term is produced by multiplying each preceding term by a fixed number, which is called a common ratio.
And from the given information:
The third term in a geometric sequence is 96 and the sixth term is 6144.
it means
and the
we know that the there is a one ratio which is same in all the two nubers between them.
And that's why
The recursive formula for a geometric sequence with common ratio r is:
.
Hence, The recursive formula for a geometric sequence is:
.

If the diameter is 12 inches, the radius is 6 inches, because the radius is half the diameter.
Given the formula
we have
When you fold the circle in half, the resulting figure has half the area.
So, you start with a circle with area
You fold it once and you have a semicircle with area
You fold it twice and you have a quarter circle with area
