What does Geometric Series represent?
A geometric series represents the partial sums of a geometric sequence. The nth term in a geometric series with first term a and common ratio r is:T(n) = a(1 - r^n)/(1 - r)

What does summation of infinite series?
The summation of a geometric series to infinity is equal to a/1-rwhere a is equal to the first term and r is equal to the common difference between the terms.
A geometric progression has a common ratio -1/2 and the sum of its first 3 terms is 18. Find the sum to infinity?
The sum to infinity of a geometric series is given by the formula Sā=a1/(1-r), where a1 is the first term in the series and r is found by dividing any term by the term immediately before it.
What does Geometric Series represent?
A geometric series represents the partial sums of a geometric sequence. The nth term in a geometric series with first term a and common ratio r is:T(n) = a(1 - r^n)/(1 - r)
What does an equal in geometric series?
Geometric series may be defined in terms of the common ratio, r, and either the zeroth term, a(0), or the first term, a(1).Accordingly,a(n) = a(0) * r^n ora(n) = a(1) * r^(n-1)
What is the difference between an arithmetic series and a geometric series?
An arithmetic series is the sequence of partial sums of an arithmetic sequence. That is, if A = {a, a+d, a+2d, ..., a+(n-1)d, ... } then the terms of the arithmetic series, S(n), are the sums of the first n terms and S(n) = n/2*[2a + (n-1)d]. Arithmetic series can never converge.A geometric series is the sequence of partial sums of a geometric sequence. That is, if G = {a, ar, ar^2, ..., ar^(n-1), ... } then the terms of the geometric series, T(n), are the sums of the first n terms and T(n) = a*(1 - r^n)/(1 - r). If |r| < 1 then T(n) tends to 1/(1 - r) as n tends to infinity.
How is emailing a joke like a geometric series?
Emailing a joke is like a geometric series because each time the joke is passed along, it has the potential to reach more and more people exponentially, similar to how each term in a geometric series is multiplied by a constant factor. Just as the sum of a geometric series can grow rapidly, the spread of a joke can escalate quickly as recipients share it with others. Additionally, the initial joke serves as the first term, while the act of forwarding it represents the common ratio that drives its expansion.
How do you find the first term of a geometric series?
The answer depends on what information you have been provided with.
What is the 7th term in the geometric sequence whose first term is 5 and the common ratio is -2?
Find the 7th term of the geometric sequence whose common ratio is 1/2 and whose first turn is 5
What is the 6th term of the geometric sequence below?
To find the 6th term of a geometric sequence, you need the first term and the common ratio. The formula for the nth term in a geometric sequence is given by ( a_n = a_1 \cdot r^{(n-1)} ), where ( a_1 ) is the first term, ( r ) is the common ratio, and ( n ) is the term number. Please provide the first term and common ratio so I can calculate the 6th term for you.
What are the formulas for geometric sequences and series?
In a geometric sequence, each term is found by multiplying the previous term by a constant ratio ( r ). The ( n )-th term can be expressed as ( a_n = a_1 \cdot r^{(n-1)} ), where ( a_1 ) is the first term. For the sum of the first ( n ) terms of a geometric series, the formula is ( S_n = a_1 \frac{1 - r^n}{1 - r} ) for ( r \neq 1 ), while for an infinite geometric series, if ( |r| < 1 ), the sum is ( S = \frac{a_1}{1 - r} ).
What is the 12th term of a geometric sequence in which the common ratio is 2 and the first term is 12?
