Hi all, I am interested in using some type of list or table in-built Mathematica function to generate a list, where the elements of the new list not only depends on the input values of a previously defined list of triplets which I denote as 'a', but also depends on the output value of the previous element of the new list. In this sense I will provide the list of triplets, the function f which takes the triplets as inputs, and the first element of the new list. Then the list should generate itself.

I provide a simple example, not the actual problem, where I use the % symbol in Mathematica to assign the previous cell output to the next iteration. But of course this is not efficient for long triplet lists. Can anyone advise on a more efficient way of doing this type of problem? Many thanks.
