According to Wittgenstein's Finite Rule Paradox every finite sequence of numbers can be a described in infinitely many ways and so can be continued any of these ways - some simple, some complicated but all equally valid. Conversely, it is possible to find a rule such that any number of your choice can be the next one.
The simplest rule is un = 18 - 3n
Each term is derived from previous term by subtracting 3, so the sequence is 15 12 9 6 3 0 etc
15 is 1st term
12 is 2nd term and 12 = 15 - 3(1)
9 is 3rd term and 9 = 15 - 3(2)
6 is 4th term and 6 = 15 - 3(3)
so the Nth term is 15 - 3(N-1)
eg if N=6 then the 6th term is 15 - 3(5) = 15 - 15 = 0

I'm seeing a lot of confused, uneducated answers. Here's the answer you want:
-3n + 18
or
-3(n - 1) + 15
To find the formula for an arithmetic sequence/series, use the formula d(n-1) + a, where d is the common difference (in this case, each term is 3 LOWER than the last, so d=-3) and a is the first term in the sequence (in this case, a = 15)
This gives us -3(n - 1) + 15
= -3n + 3 + 15
= -3n + 18

what is the nth term for 12 10 8 6?
The nth term would be -2n+14 nth terms: 1 2 3 4 Sequence:12 10 8 6 This sequence has a difference of -2 Therefore it would become -2n. Replace n with 1 and you would get -2. To get to the first term you have to add 14. Therefore the sequence becomes -2n+14. To check your answer replace n with 2, 3 or 4. You will still obtain the number in the sequence that corresponds to the nth term. :)
What is the nth term of 12 19 26 33 40?
Here are the first five terms of a sequence. 12 19 26 33 40 Find an expression for the nth term of this sequence.
What is the nth term of the sequence 18 12 6 0 -6?
To find the nth term of a sequence, we first need to identify the pattern or rule that governs the sequence. In this case, the sequence is decreasing by 6 each time. Therefore, the nth term can be represented by the formula: 18 - 6(n-1), where n is the position of the term in the sequence.
What is the nth term for 12 10 8 6 4?
The given sequence is decreasing by 2 each time, starting from 12. To find the nth term, we can use the formula for an arithmetic sequence: (a_n = a_1 + (n-1)d), where (a_n) is the nth term, (a_1) is the first term, (n) is the term number, and (d) is the common difference. In this case, (a_1 = 12), (d = -2), and we need to find the general formula for the nth term. Therefore, the nth term for the sequence 12 10 8 6 4 is (a_n = 12 + (n-1)(-2)), which simplifies to (a_n = 14 - 2n).

What is the nth term for 98 94 90 84?
To find the nth term in a sequence, we first need to identify the pattern or formula that describes the sequence. In this case, the sequence appears to be decreasing by 4, then decreasing by 6, and finally decreasing by 10. This suggests a quadratic pattern, where the nth term can be represented as a quadratic function of n. To find the specific nth term for this sequence, we would need more data points or information about the pattern.
