Question
One number does not fit into the given factorial series. Identify it. 3, 6, 24, 120, 720, 800
Solution
Given: 3, 6, 24, 120, 720, 800 Look at the numbers: 6 = 3! 24 = 4! 120 = 5! 720 = 6! All these numbers are factorials of natural numbers. But, 800 is not the factorial of any whole number. Therefore, 800 does not fit the factorial series. Thus, correct option is (d).
