Explicit formulas can be used to determine the number of terms in a finite arithmetic sequence. We need to find the common difference, and then determine how many times the common difference must be added to the first term to obtain the final term of the sequence. How To:...

The formation of terms in arithmetic progression (AP) and its sum to n terms has been given in the Bakshali work. As an illustration of this, we will present an example found in the Bakshali work. Example “A person travels a‘yojanas’ in the first day and b‘yojanas’ more on ea...
The sum of the first n terms of an arithmetic sequence is given by Sn=n⋅a1+an2Answer and Explanation: We are given that the sum of 6 consecutive integers is 519. Let x be the first term in the sequence. Then, using the formula for......
