I will provide the nth term for each sequence below based on the search results:

  1. 3, 4, 5, 6, 7... The nth term for this sequence is n + 2.

  2. 3, 5, 7, 9, 11... The nth term for this sequence is 2n + 1.

  3. 1, 4, 9, 16... The nth term for this sequence is n^2.

  4. -1, 1... The nth term for this sequence is (-1)^n.

Its worth noting that the nth term of an arithmetic sequence can be found using the formula an = a1 + (n-1)d, where a1 is the first term, d is the common difference, and n is the term number. The common difference is found by subtracting any term from the next term in the sequence.
