If you mean -1 3 7 11 15 then the nth term is 4n-5 and so the next term will be 19
It is: nth term = 5-4n and so the next term will be -19
The nth term is: 5-2n
The Nth term for a triangle number is: 0.5n(n+1)
(2n-1)(-1)n
It is: nth term = 29-7n

Well, darling, it looks like we have a arithmetic sequence going on here. The common difference between each term is 7, so to find the nth term, you can use the formula a_n = a_1 + (n-1)d. In this case, a_1 is 1 and d is 7, so the nth term would be 1 + (n-1)7, which simplifies to 7n - 6. Voila!
The nth term is -7n+29 and so the next term will be -6
If you mean -1 3 7 11 15 then the nth term is 4n-5 and so the next term will be 19
It is: nth term = 5-4n and so the next term will be -19
The nth term is 4n-1 and so the next term will be 19
The nth term is 22n and so the next number will be 5*22 = 110
The nth term for that arithmetic progression is 4n-1. Therefore the next term (the fifth) in the sequence would be (4x5)-1 = 19.
