Question

Deremine if the sequence is arithmetic if it is find the common difference(d) and tha next 3 terms in sequence





​

Answer 1

To find the "nth" term of an arithmetic sequence, start with the first term, a(1). Add to that the product of "n-1" and "d" (the difference between any two consecutive terms). For example, take the arithmetic sequence 3, 9, 15, 21, 27.... a(1) = 3. d = 6 (because the difference between consecutive terms is always
