Clearly here the nth term isn't n25.

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
It is: 27-2n
If the nth term is n*7 then the first 5 terms are 7, 14, 21, 28, 35.

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
You can see that all the numbers go up by 7. This means that the first part of the nth term rule for this sequence is 7n. Now, you have to find out how to get from 7 to 3, 14 to 10, 21 to 17 ... this is because we are going up in the 7 times table. To get from the seventh times table to the sequence, you take away four. So the answer is : 7n-4
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.
