![]() ![]() What is the common ratio of the following geometric sequence? Then you can check if you calculated correctly using the geometric sum calculator. The final result makes it easier for you to compute manually. Now you have to multiply both od the sides by (1-r): Here’s a trick you can employ which involves modifying the equation a bit so you can solve for the geometric series equation: Still, understanding the equations behind the online tool makes it easier for you. This is why a lot of people choose to use a sum of geometric series calculator rather than perform the calculations manually. However, this equation poses the issue of actually having to calculate the value of the geometric series. Mathematically, geometric sequences and series are generally denoted using the term a∞. However, most mathematicians won’t write the equation this way. This is the first geometric sequence equation to use and as you can see, it’s extremely simple. This means that every term after the symbol gets summed up. To modify the equation and make it more efficient, let’s use the mathematical symbol of summation which is ∑. Although there is a basic equation to use, you can enhance your efficiency by playing around with the equation a bit. If you want to perform the geometric sequence manually without using the geometric sequence calculator or the geometric series calculator, do this using the geometric sequence equation.
