Concept:Check whether each term follows the pattern of a cube of consecutive numbers starting from 2, with the same number added to it.Explanation:10=23+230=33+368=43+4130=53+5Following this pattern, the next term should be:63+6=216+6=222But the given term is 221, which is one less than the expected value.Therefore, 221 is the wrong number in the series.
