14+9n
The sequence 13, 14, 15, 16, 17, 18, 19, 20 is an arithmetic progression where each term increases by 1. The nth term can be expressed by the formula ( a_n = 12 + n ), where ( n ) is the term number starting from 1. For example, for ( n = 1 ), ( a_1 = 12 + 1 = 13 ), and for ( n = 8 ), ( a_8 = 12 + 8 = 20 ).
They are: nth term = 6n-4 and the 14th term is 80

14+9n
This is an arithmetic sequence which starts at 14, a = 14, and with a common difference of -1, d = -1. We can use the nth term formula an = a + (n - 1)d to get an = 14 + (n - 1)(-1) = 14 - n + 1 = 15 - n.
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).
It is: nth term = -4n+14
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. :)
They are: nth term = 6n-4 and the 14th term is 80
The nth term is 2 + 3n.
The nth term is 3n+2 and so the next number will be 17
42
Clearly here the nth term isn't n25.
