I'm not sure if this is even the correct section, but I think I understand that the subscript denotes place in a sequence, so this is my best guess. I can't figure out where to go from there. Most information seems to be about defining the sequence based on variables, but I have been given two suscripted numbers to subtract and can't find rules about how to do that. Here is the problem:
