Geometric Sequence Definition:
Basically, a sequence is regarded as a set. This set contains numbers that are defined in particular orders. Coming to the point now, a geometric sequence is what is obtained by finding the product of the previous number in the series by a common ratio.
This common ratio is always a fixed number and does not change, until the previous or next number changes.
Example:
In the following table below, you will see how common difference has impact on changing a geometric sequence:
| First Term | Term-to-Term Rule | First 5 Terms |
| 3 | Multiply by 3 | 3,9,27,81,243,… |
| 5 | Multiply by | 5,10,20,40,80,… |
| 0.8 | Multiply by 5 | 0.8,4,20,100,500,… |
Geometric Sequence Formula:
The geometric sequence calculator makes use of the following equation to calculate this particular series:
an =a1(r)n-1
Where:
r = the common ratio of the sequence
a_n = nth term of the sequence
a_1 = first term of the sequence
n = position of the number or value in sequence
Continuing a Geometric Sequence:
Here are the crucial points that you must keep in mind if you want to continue a geometric sequence:
- Pick out the first two terms in the sequence.
- To determine the common ratio r, divide the second term by the first term.
- To get the following term, multiply the previous term in the series by the common ratio.
- For every new word, repeat.
All of these points are also considered by the geometric sequence calculator to calculate instant results without any trouble.
Example:
Let us resolve an example to clarify your concept in more detail!
Statement:
Calculate the geometric sequence for the following data:
0.999…
Solution:
Here we have
0.999=0.9+0.09+0.009+…
0.999=0.9*0.10+0.9*0.11+0.9*0.12+…
k=0∞0.9*0.1k
The final series is:
k=0∞0.9*0.1k=0.9(1/1-0.1)=0.9(1/0.9)=1
Which is the final answer then can also be checked by using the free geometric sequence calculator in seconds.
How To Use a Geometric Series Calculator?
Using this tool is quite straightforward. You just need to stick to a couple of points to get your desired results. These are:
- From the top drop-down list, select the parameter you wish to calculate
- After doing this, you need to enter the required values in their respective fields
- Tap Calculate and get the accurate calculations in seconds
Wrapping It Up:
Calculating geometric sequence by hand is not a very difficult process. All you need to know is the parameters in the formula and recognize them one by one in the sequence. Once you find all of these, just put them in the formula and start your calculations. And if you feel any doubt regarding calculations, you may cross-check the results by using the geometric sequence calculator.
