A Correct answer
Explanation

The series follows a pattern of division: 1080 / 2 = 540, 540 / 3 = 180, 180 / 4 = 45, 45 / 5 = 9, 9 / 6 = 1.5.

AI explanation

The series is divided by decreasing integers: 1080/6=180, wait, let's look at the end: 45/9=5, 9/1.5=6, 180/45=4. So the divisors are 4, 5, 6, meaning the missing term divided by 5 gives 180, so the missing term is 180*5=900, wait, let's re-evaluate: 540/180=3, so the divisors are 2, 3, 4, 5, 6. Thus, 1080/2=540. The result is 540.
