arithmetic sequence, the fixed logic or rule is that the difference of any two consecutive terms is common, this implies that for finding any term we have to just add this common difference in its previous term. In mathematical form, this is described ...
Closed Form Arithmetic Sequence Additionally, we will discover a superb procedure for finding the sum of an Arithmetic and Geometric sequence, using Gauss’s discovery ofreverse-addandmultiply-shift-subtract, respectively. Example Suppose we wanted to find the sum of the following sequence: 1,3,5...

The "findNthTermArithmetic()" function takes three parameters: x (the first term of the sequence), d (the common difference), and n (the term number to find). The function uses recursion to find the nth term of the arithmetic sequence. If n is 1, it means we have reached the fi...
