Im not a guru but one solves equations, not sequences.  A sequence is just a set of constants.   Progression sounds like new math for sequence?

We can't see your link unless we are members of your group.

the following sequence of numbers arose experimentally ( at least close approximations to them and it turns out the difference is rounding error ) However, I can't quite see a way to work out the rule. Can you?


2,  6,  20  , 70  , 252 .....


I am not interested in the solution - I am asking if in this day and age  there is a website or computer  program on the internet where by you INPUT 2  6 20  70 252 then the program solves and gives you the next number ?
