7 - 4n where n denotes the nth term and n starting with 0
The nth term in the sequence -5, -7, -9, -11, -13 can be represented by the formula a_n = -2n - 3, where n is the position of the term in the sequence. In this case, the common difference between each term is -2, indicating a linear sequence. By substituting the position n into the formula, you can find the value of the nth term in the sequence.
1 4 9 is a series of squared numbers. The nth term is [ n squared ]
Un = (-1)n*(2n - 1)
