The nth term in this sequence is 4n + 3.
It is: 2n+9
The nth term for that arithmetic progression is 4n-1. Therefore the next term (the fifth) in the sequence would be (4x5)-1 = 19.
15
The next term is: 15+4 = 19 The nth term is: 4n-5
The nth term in this sequence is 4n + 3.
If you mean: 15 11 7 3 then the nth term is 19-4n
The nth term is 4n-1 and so the next term will be 19
It is: 2n+9
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
Double it minus the previous number.
The nth term is: 2n+7 and so the next number will be 19
The nth term for that arithmetic progression is 4n-1. Therefore the next term (the fifth) in the sequence would be (4x5)-1 = 19.
The simplest, out of infinitely many possible answers, is the linear polynomial,U(n) = 4n - 1 for n = 1, 2, 3, ...
Well, honey, the odd numbers between 10 and 20 are 11, 13, 15, 17, and 19. It's not rocket science, just simple math. So, there you have it, darling. Hope that clears things up for you.
