It is: 2n+9
2n + 1
The nth term in this sequence is 4n + 3.
The nth term is 2n+5 and so the next number is 17
The sequence is simply achieved by adding 2 to each value9+2=1111+2=1313+2=1515+2=1717+2=1919+2=21so the nth term can be calculatedThe value of the nth term = the value of (nth-1 term) +2.
It is: 2n+9
2n + 1
The nth term is: 2n+7 and so the next number will be 19
The nth term in this sequence is 4n + 3.
If you mean: 15 11 7 3 then the nth term is 19-4n
If you mean -1 3 7 11 15 then the nth term is 4n-5 and so the next term will be 19
The nth term is 2n+5 and so the next number is 17
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
(2n-1)(-1)n
The sequence is simply achieved by adding 2 to each value9+2=1111+2=1313+2=1515+2=1717+2=1919+2=21so the nth term can be calculatedThe value of the nth term = the value of (nth-1 term) +2.
The nth term for that arithmetic progression is 4n-1. Therefore the next term (the fifth) in the sequence would be (4x5)-1 = 19.
