Explanation

The sequence follows the pattern of adding 103 to each term: 206 + 103 = 309, 309 + 103 = 412, 412 + 103 = 515, 515 + 103 = 618, 618 + 103 = 721.

AI explanation

This is a simple addition series with a common difference of 103. We add 103 to 206 to get 309, add 103 to 309 to get 412, and add 103 to 412 to find the missing term of 515. This is confirmed by adding 103 to 515 to get 618.
