What is the 12th term of the geometric sequence in number 4?

⇒ 12th term is 708588 .

What determines the nth term in a geometric sequence?

The n th term of a geometric sequence with initial value n and common ratio r is given by: an=arn−1 a n = a r n − 1 .

How do you get the next term of a geometric sequence given the first term and a common ratio?

Writing Terms of Geometric Sequences For instance, if the first term of a geometric sequence is a1=−2 a 1 = − 2 and the common ratio is r=4 , we can find subsequent terms by multiplying −2⋅4 − 2 ⋅ 4 to get −8 then multiplying the result −8⋅4 − 8 ⋅ 4 to get −32 and so on.

How do you find the tenth term in a geometric sequence?

6. How do you find the nth term of a geometric progression with two terms? First, calculate the common ratio r by dividing the second term by the first term. Then use the first term a and the common ratio r to calculate the nth term by using the formula an=arn−1 a n = a r n − 1 .

What is the next term of the geometric sequence?

Geometric sequences have a fixed ratio between successive pairs of terms. To find the next term in the sequence just multiply the previous term by the common ratio. The general term of the sequence can be written: an=a1⋅rn−1. where a1 is the first term and r the common ratio.

What is the 12th term of the arithmetic sequence?

∴ , the 12th term is −46 .

How do you find the first term of a geometric sequence?

To find the sum of the first S n terms of a geometric sequence use the formula S n = a 1 ( 1 − r n ) 1 − r , r ≠ 1 , where n is the number of terms, a 1 is the first term and r is the common ratio .

What is geometric progression in math?

A Geometric Progression is a sequence in which each term is obtained by multiplying a fixed non-zero number to the preceding term except the first term. The fixed number is called common ratio. The common ratio is usually denoted by r. General form of geometric progression :

What is the use of geometric sequences calculator?

Geometric sequences calculator This tool can help you to find term and the sum of the first terms of a geometric progression. Also, this calculator can be used to solve more complicated problems. For example, the calculator can find the first term () and common ratio () if and.

How do you find the sum of the first terms?

Sum of the First Terms of a Geometric Sequence. If a sequence is geometric there are ways to find the sum of the first terms, denoted , without actually adding all of the terms. To find the sum of the first terms of a geometric sequence use the formula , where is the number of terms, is the first term and is the common ratio .
