The nth term in this sequence is 4n + 3.
The nth term is 4n-1 and so the next term will be 19
If you mean: 15 11 7 3 then the nth term is 19-4n
It is: nth term = 5-4n and so the next term will be -19
If you mean -1 3 7 11 15 then the nth term is 4n-5 and so the next term will be 19
Double it minus the previous number.
The nth term for that arithmetic progression is 4n-1. Therefore the next term (the fifth) in the sequence would be (4x5)-1 = 19.
It is 4n -1 and so the next term will be 23
each time the number increases by 8 and the original number was 3.This means that nth term = 3+(n-1)8ie. the fourth term 27 would be 3 + (4-1)x8 = 3+24 = 27
The simplest, out of infinitely many possible answers, is the linear polynomial,U(n) = 4n - 1 for n = 1, 2, 3, ...
The nth term of the sequence is 2n + 1.
