What is the general rule for the arithmetic sequence 15 12 9 6?
Wiki User
∙ 11y ago
There are two ways to say the general rule. They both mean exactly
the same thing, and they both generate the same sequence:
1). Starting with 15, each new term is 3 less than the one before it.
2). The nth term of the sequence is [ 18 - 3n ] or [ 3 times (6 - n) ].

Is 2 6 18 54 an arithmetic sequence?
No it is not.U(2) - U(1) = 6 - 2 = 4U(3) - U(2) = 18 - 6 = 12Since 4 is different from 12, it is not an arithmetic sequence.
What is the d value of the following arithmetic sequence 16 9 2 5 12 19?
The sequence in the question is NOT an arithmetic sequence. In an arithmetic sequence the difference between each term and its predecessor (the term immediately before) is a constant - including the sign. It is not enough for the difference between two successive terms (in any order) to remain constant. In the above sequence, the difference is -7 for the first two intervals and then changes to +7.
What is the nth term of the following arithmetic sequence 12 16 20 24 28?
