Determine whether each infinite geometric series diverges or converges.
The series converges.
If the series converges, state the sum. 4+2+1+ . . .
The sum of the infinite series is 8
What is the sum of the infinite series?
Given:
[tex]a(\text{ the first term})=4\\\\r(\text{ the common ratio})= \frac{a_2}{a_1} = \frac{2}{4}=\frac{1}{2}[/tex]
Since , [tex]\vert r\vert < 1[/tex] , the infinite series converges.
The sum of infinite geometric series is:
[tex]S_\infty=\frac{a}{1-r} ; -1 < r < 1\\\\S_\infty=\frac{4}{1-\frac{1}{2} } =\frac{4}{\frac{1}{2} }=8[/tex]
The sum of the infinite series is 8
What is an infinite geometric series?
- The result of an endless geometric sequence is an infinite geometric series.
- There would be no conclusion to this series.
- The total of all finite geometric series can be determined.
- However, if the common ratio of an infinite geometric series is bigger than one, the terms in the sequence will grow steadily larger, and adding the larger numbers together will not yield a solution.
