I have discovered the next number in the series is 74 (4 8 15 16 23 42 74). There is a very neat way to arrive at this number and a surprising result. Please let me know if adding to the sequence is in your plans, if it would be a spoiler if I revealed the method to get to 74.

If this is totally befuddling to you, I will explain and you can choose to use it or not. Just let me know how I can give you this information privately.

aaayeee
