Question

The first three terms of a sequence are given. Round to the nearest thousandth(if necessary) 18,12,8 find the 10th term

Answer 1

Answer:

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 6.
