The equation could be used to calculate the sum of the geometric series is 
<h3>Sum of geometric sequence</h3>
Geometric sequence are sequence that increase expoentially. The formula for calculating the sum of an exponential sequence is expressed as:

where
- a is the first term
- n is the number of terms
- r is the common ratio
From the given sequence
a= 1/3
r = 2/9 * 3 = 2/3
Substitute into the formula

Hence the equation could be used to calculate the sum of the geometric series is

The solution is the point where the two lines intersect. In this case it is (-6,-4). So the answer would be C.
You could put it in standard form if thats what you mean. in that case its "two thousand seven hundred" or you could also do it in another form which in that case its "2000 + 700"
When we have two or more given numbers, we can find the largest factor that both numbers have in common. This is called the GCF or the Greatest Common Factor. ... Example: Find the GCF of 64 and 96. tep 1:
