The nth term in this sequence is 4n + 3.
2n + 1
tn = 15 - 4n (n = 1,2,3, ... )
The nth term is 18 -3n and so the next term will be 3
1...2....3....43...7...11..157 - 3 = 411 - 7 = 415 - 11 = 4(the start of the nth term is 4n)4 x 1 = 4(but the first term is 3, so...)4 -1 = 3nth term = 4n - 1
The nth term in this sequence is 4n + 3.
If you mean -1 3 7 11 15 then the nth term is 4n-5 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
The nth term is 4n-1 and so the next term will be 19
2n + 1
tn = 15 - 4n (n = 1,2,3, ... )
Double it minus the previous number.
The nth term is 18 -3n and so the next term will be 3
1...2....3....43...7...11..157 - 3 = 411 - 7 = 415 - 11 = 4(the start of the nth term is 4n)4 x 1 = 4(but the first term is 3, so...)4 -1 = 3nth term = 4n - 1
It is 4n -1 and so the next term will be 23
The nth term is 2n+5 and so the next number is 17
