pattern - What is the next number? 24,54,90,120,168,210,240,288,360,440




Question : What is the next number in the following sequence? (not finite)



$$\large24,54,90,120,168,210,240,288,360,440,\dots$$



My Solution




  • I'm trying a closed form solution




  • I tried computing the differences- they don't converge





  • Tried finding the relationship between their binary equivalents




  • A trivial observation : all numbers are divisible by $6$ except $440$




Edit-1: Seeing the downvotes, I want to clarify something: All I'm trying to do is to find a solution (an expresssion) that represents the sequence


Edit-2 : This question was given by my Math Teacher as a fun exercise in puzzle solving . It is not for a graded homework
