The nth term of an arithmetic sequence is given by : an=a1+(nā1)d an = a1 + (nā1)d To find the nth term, first calculate the common difference, d. Next multiply each term number of the

similarly, Nth term = a+ (n-1)d. Steps to find the nth term. Step 1: At first find the first and 2nd term, that is a 1 and a 2. Step 2: Then find the common difference between
