Question

what formula is used to find COMMON DIFFERENCE IN AP​

Answer 1

• Since the difference is the same for each set, you can say that the common difference is 3. Therefore, you can say that the formula to find the common difference of an arithmetic sequence is: d = a(n) - a(n - 1), where a(n) is the last term in the sequence, and a(n - 1) is the previous term in the sequence
