Webwhen you take the 3 numbers in AP as a-d, a and a+d, you can cancel out the 2 ds ( d and -d) and get the value of a quickly. You can also take the number as a, a+d and a+2d but this will make your calculation complicated and you will find it diificult to get the final value of a and d. Lawrence C. FinTech Enthusiast, Expert Investor, Finance at ... WebKey Takeaways. An arithmetic sequence is a sequence where the difference d between successive terms is constant. The general term of an arithmetic sequence can be written in terms of its first term a1, common difference d, and index n as follows: an = a1 + (n − 1)d. An arithmetic series is the sum of the terms of an arithmetic sequence.
