Explanation

7201, 7202 (x1+1), 3603 (x0.5+1), 1204 (x1/3+1), 306 (x1/4+1). 1204/4 + 1 = 301 + 1 = 302. The term 306 is incorrect.

AI explanation

The pattern is dividing by consecutive integers starting from 1 and then adding 1. Dividing 7201 by 1 and adding 1 gives 7202. Dividing 7202 by 2 and adding 2 gives 3603. Continuing, dividing 3603 by 3 and adding 3 gives 1204, and dividing 1204 by 4 and adding 4 gives 305. Since the given term is 306, it is the wrong number; checking further, 305 divided by 5 plus 5 is 66, which confirms the pattern.
