A General Note: Arithmetic Sequence. What is the common difference in the following arithmetic sequence? Each term increases or decreases by the same constant value called the common difference of the sequence. If common difference is positive (d > 0), the sequence tends to positive infinity and, if common difference is negative (d < 0), it tends to the negative infinity. Arithmetic Sequence or Arithmetic Series is the sum of elements of Arithmetic Progression having a common difference and an nth term. The values of the truck in the example are said to form an arithmetic sequence because they change by a constant amount each year. If you take any number in the sequence then subtract it by the previous one, and the result is always the same or constant then it is an arithmetic sequence. When it comes to an arithmetic sequence, the variation is in a linear form. ", "acceptedAnswer": { "@type": "Answer", "text": "
