![]() ![]() Now that you know what a geometric sequence is and how to write one in both the recursive and explicit formula, it is time to apply your knowledge and calculate some stuff! With our geometric sequence calculator, you can calculate the most important values of a finite geometric sequence. But if we consider only the numbers 6, 12, 24 the GCF would be 6 and the LCM would be 24. For example, in the sequence 3, 6, 12, 24, 48 the GCF is 3 and the LCM would be 48. Conversely, the LCM is just the biggest of the numbers in the sequence. This means that the GCF (see GCF calculator) is simply the smallest number in the sequence. Indeed, what it is related to is the [greatest common factor (GFC) and lowest common multiplier (LCM) since all the numbers share a GCF or a LCM if the first number is an integer. First of all, we need to understand that even though the geometric progression is made up by constantly multiplying numbers by a factor, this is not related to the factorial (see factorial calculator). We also include a couple of geometric sequence examples.īefore we dissect the definition properly, it's important to clarify a few things to avoid confusion. If you are struggling to understand what a geometric sequences is, don't fret! We will explain what this means in more simple terms later on, and take a look at the recursive and explicit formula for a geometric sequence. You need to set the "Use regular expression to parse number" checkbox and enter a regular expression and match group, which will be used to extract the number.ĭefault regular expression matches the line where the number is placed at the beginning of the line.The geometric sequence definition is that a collection of numbers, in which all but the first one, are obtained by multiplying the previous one by a fixed, non-zero number called the common ratio. Your text file will probably include additional text, something like:įor that case, you can use a regular expression to extract the number from the line and then check the sequence. The reason for the second option is that your list is unlikely to include just numbers. You can set the "Use regular expression to parse number" checkbox to parse the line of your text file with regular expression.If you uncheck it, you will get a list of all numbers in a gap, i.e. You can set the "Collapse gaps" checkbox to output gaps in a collapsed form, in other words, taking 8 - 11 as an example, the 8 is the start of the gap and 11 is the end.You can paste in a list of numbers, and it will display all the missing numbers and gaps it was able to find in the sequence, bounded by the first and the last line of the list. Of course, in this example, it is easy to see the problems just by looking at numbers, but if we were talking about thousands of numbers, it would be too cumbersome to locate the gaps by eye. In the example above, 5 is missing, and there are two gaps: between 8 and 11 and also between 14 and 17. However, there are some missing numbers and gaps. Let's suppose you have a text file of consecutive numbers, such as below, with each number on its own line: If you are looking for math problem solving, then it is probably about arithmetic sequence or geometric sequence - please look at Arithmetic sequence calculator and problems solver or Geometric sequence calculator and problems solver Disclaimer: This calculator was made for a specific purpose to find gaps in a continuous number sequence.
