The nth term in this sequence is 4n + 3.

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

One of the infinitely many possible rules for the nth term of the sequence is t(n) = 4n - 1

3 11

The nth term is 4n-1 and so the next term will be 19

I believe the answer is: 11 + 6(n-1) Since the sequence increases by 6 each term we can find the value of the nth term by multiplying n-1 times 6. Then we add 11 since it is the starting point of the sequence. The formula for an arithmetic sequence: a_{n}=a_{1}+(n-1)d

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

It works out as -5 for each consecutive term

The 'n'th term is [ 4 - 3n ].

The 'n'th term is [ 4 - 3n ].

The 'n'th term is [ 4 - 3n ].

The nth term is: 3n+2 and so the next number will be 20
