Familiar Thursday evening situation: On a flight returning home. Have not posted a puzzle in some time. So, here is one…
What is the next number in the following sequence?
4, 6, 12, 18, 30, 42, 60, 72, 102, …
(If you know the answer send me a personal message)
Disclaimer: I remember this puzzle vividly from my college days because after two days I simply gave up 🙁
