Correct answer
Explanation
Two interleaved patterns: positions 1,3,5,7 increase by 1 (3, 4, 5, 6) and positions 2,4,6 decrease by 2 (8, 6, 4). The seventh term follows the first pattern: 5 + 1 = 6. The eighth term follows the second pattern: 4 - 2 = 2.
AI explanation
This is two interleaved sequences: the odd-position terms increase by 1 (3, 4, 5, 6...) and the even-position terms decrease by 2 (8, 6, 4, 2...). Following the decreasing sub-sequence after 4 gives the next even-position term as 2.
