Want this question answered?
after -9 it is -15 then -21, -27 and the ninth is -36
23-2nthis guy has a great way of explaining it, so look at his...What_is_the_nth_term_for_3_7_11_15_19

The given sequence (7, 14, 21, 28, 35,....) is an arithmetic sequence where each term increases by 7. The nth term of the given sequence is 7n
The nth term is 25-4n and so the next term will be 5
It is 4n+5 and so the next term will be 25
Clearly here the nth term isn't n25.
It is: 27-2n
81
A single number, such as 1521273339 does not define a sequence. There is no nth term for a signle number.
after -9 it is -15 then -21, -27 and the ninth is -36
1st term= 3 2nd term = 5 Nth term = 2n+1 10th term= 21 = 2(10)+1
tn = 2x2 + 3 where x = 1, 2, 3, ...
The nth term is n2 + 4n.
The nth term of an arithmetic sequence is given by. an = a + (n – 1)d. The number d is called the common difference because any two consecutive terms of an. arithmetic sequence differ by d, and it is found by subtracting any pair of terms an and. an+1.
