The series alternates between two patterns: 80, 70, 60 (subtract 10) and 10, 15, 20 (add 5). The next term follows the second pattern.

AI explanation

This question uses two interwoven series, one starting with 80 and decreasing by 10, and the other starting with 10 and increasing by 5. The sequence splits into alternate terms: 80, 70, 60 for the first pattern and 10, 15 for the second. Following the increasing pattern of adding 5, the next term after 15 is 20. The result is 20.
