5n-5, because its the 5 time table (called 5n) minus 5 each time
15(1)
The nth term in this sequence is 4n + 3.
The nth term is: 5n
1, 3, 6, 10, 15 ,21 The nth term for the sequence (where you replace n with the term you want to find) is: (n(n+1))/2
The nth term is 18 -3n and so the next term will be 3
Say if you had the pattern 15 20 25 30 35 40 45 50 To find the nth term you have to see what the gap between the numbers is. In our case this is 5. Then you have to find out what the difference between the gap and the first number. In this sequence it is 10. So your answer would be..... 5n+10 That's how you find the nth term.

To find the nth term of the sequence 5, 15, 29, 47, 69, we first determine the differences between consecutive terms: 10, 14, 18, and 22. The second differences are constant at 4, indicating that the nth term is a quadratic function. By fitting the quadratic formula ( an^2 + bn + c ) to the sequence, we find that the nth term is ( 2n^2 + 3n ). Thus, the nth term of the sequence is ( 2n^2 + 3n ).
The nth term in this sequence is 4n + 3.
It is: nth term = 29-7n
If you mean: 15 11 7 3 then the nth term is 19-4n
The nth term is: 5n
It is: nth term = 5-4n and so the next term will be -19
1, 3, 6, 10, 15 ,21 The nth term for the sequence (where you replace n with the term you want to find) is: (n(n+1))/2
The nth term is 4n-1 and so the next term will be 19
The nth term is 18 -3n and so the next term will be 3
If you mean -1 3 7 11 15 then the nth term is 4n-5 and so the next term will be 19
