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

The next term is: 15+4 = 19 The nth term is: 4n-5

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

It is 4n -1 and so the next term will be 23

The nth term of the sequence is 2n + 1.

The nth term is 2n+5 and so the next number is 17

11

The nth term is 7n-3 and so the next term will be 39

The nth term is: n^2 +2 and so the next number will be 38

(2n-1)(-1)n

0,3,8,15,24,27,32,41

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: 25-7n

7n - 3

after -9 it is -15 then -21, -27 and the ninth is -36

The nth term is: 5-2n

Un = 25 - 7n

T(n) = 12 - n2
