7 - 4n where n denotes the nth term and n starting with 0
Un = (-1)n*(2n - 1)
(2n-1)(-1)n

The answer depends on the value of B.
The nth term of the sequence is 2n + 1.
Un = 4n - 9
The "N"th term is -7. You can deduce this from: 19 - 7 = 12 - 7 = 5 - 7 = -2 - 7 = -9
7 - 4n where n denotes the nth term and n starting with 0
For an A.P., nth term of the sequence is given by 5 + (n-1)d, where d is the common difference.
2n + 1
The nth term is 7n-5 and so the 6th term will be 37
It is: nth term = 7n-9
2n+5
The nth term is: 2n+7 and so the next number will be 19
Un = (-1)n*(2n - 1)
The nth term is 2n+5 and so the next number is 17
