![]() ![]() We obtain results by multiplying the terms of a geometric sequence. Ref fig 2 belowĪ geometric sequence or geometric series is a geometric order. The reason is that if you add or subtract (also known as finding the difference), you always get the same common value. It is essential to note that the number that is added or subtracted at each level of an arithmetic sequence is called as the difference (d). 7, 3, -1, -5 …is an arithmetic sequence as each step subtracts 4. The same holds for a reverse order (in subtraction). 2, 5, 8, 11, 14….is arithmetic sequence as each step adds 3. Let us take some examples to understand better. Here, in this sequence, each number moves to the second number by adding (or subtracting 1). In the arithmetic sequence, one term goes to the next term by always adding-for example, 1, 2, 3, 4, 5 ….10, and so on. Let us understand the Arithmetic sequence formula. ![]() A geometric sequence is about multiplying (or division) in a set order. An arithmetic sequence is about addition (or subtraction) in a set order. In the geometric series, the common value is always 2. Ref the figure below, in the arithmetic sequence the difference (d) is always a standard value 7. The geometric progression goes from one term to another and multiplies or divides. An arithmetic sequence is about numbers that add or subtract. Now, the point is what is a sequence and how is it related to the subject of Mathematics.
