**How to find the common ratio of a geometric series**

Find the sum of the ?rst ?ve terms of the g.p. with ?rst term 3 and common ratio 2. 6. Find the sum of the in?nite geometric series with ?rst term 2 and common ratio 1... u1 = 16 u5 = 9 cool, now the formula for the nth term of a geometric series is: un = u1 * r^(n-1) so the nth term is u1 multiplied by r (common ratio) (n-1) times.

**SOLUTION find the common ratio of an infinite geometric**

You can put this solution on YOUR website! find the common ratio of an infinite geometric series with first term 6 and with sum 7.5 The formula for finding the sume of an infinite series is: , where S is sum, a is the first term, and r is the common ratio.... Every Geometric Sequence has a common ratio between consecutive terms. Examples include: The common ratio can be positive or negative. It can be a whole number, a fraction, or even an irrational number. No matter what value it has, it will be the ratio of any two consecutive terms in the Geometric Sequence. Therefore, to test if a sequence of numbers is a Geometric Sequence, calculate the

**The first term of a geometric sequence is 16 and the fifth**

I have a geometric series with the first term 8 and a common ratio of -3. The last term of this sequence is 52488. I need to find the sum till the n th term.... And each time I'm multiplying it by a common number, and that number is often called the common ratio. So in this case, a1 is equal to 2, and my common ratio is equal to 3. So if someone were to tell you, hey, you've got a geometric sequence. a1 is equal to 90 and your common ratio is equal to negative 1/3. That means that the first term of your sequence is 90. The second term is negative 1/3

## How To Find Common Ratio Of Geometric Series

### In mathematics, a geometric sequence, also known as a geometric progression, is a sequence of numbers where each term after the first is found by multiplying the previous one by a fixed non-zero number called the common ratio. The sum of the numbers in a geometric progression is also known as a geometric series.

- 13/02/2013 · Given a geometric series (for example: 100+50+25+....), how would I go about finding the common ratio to find the sum of this infinite geometric series? P.S. I already know the answer to the given example, but I would like to know how to find the common ratio. And I know how to find the sum, just not the "r" :
