AI explanation

The given sequence has a repeating block of four numbers: 1, 3, 5, 7. To find the 18th term, divide 18 by 4, which gives a quotient of 4 and a remainder of 2. The remainder 2 means the 18th term corresponds to the second term of the repeating block. Therefore, the 18th term of the sequence is 3.
