Solve for Sum of the sequence
The above sequence represents sum of Geometric Sequence and will be solved using:
But first, we need to get the number of terms in the sequence using:
Where
So, we have:
Apply law of indices:
Apply law of indices:
Represent 1 as
They have the same base:
So, we have
Solve for n
So, there are 1893 terms in the sequence given.
Solving further:
Where
So, we have:
Simplify the numerator
Open Bracket
Hence, the sum of the sequence is:

Answer:
x^2 + y^2 = 3^2
Step-by-step explanation:
Start with (x - h)^2 + (y - k)^2 = r^2.
If the center is at (0, 0), we then have x^2 + y^2 = r^2.
If this circle passes through (0, 9), then 0^2 + 9^2 = r^2, and r must be 3.
Then the standard equation of this circle i
x^2 + y^2 = 3^2
