Show answer & explanation
Correct answer: A
Pattern: the sequence repeats a run of descending odd numbers followed by a run of descending even numbers.
Odd run: 9, 7, 5, 3, 1
Even run: 8, 6, 4, 2
These two runs repeat in order: odd run then even run, then odd run again.
Since the last term shown is 1 (the end of the odd run), the sequence continues with the start of the even run, which is 8.
Answer: 8
