Dear student,

The 'n' in the figure denotes the number and the sequence of amino
acids arranged in the polypeptide chain of the primary structure of
the protein If 'n' is the starting number of amino acid in the
polypeptide chain, then 'n-1' will be amino acid residue present
before the 'n' amino acid and 'n+1' will be the amino acid residue
present after the main amino acid 'n'
Hope this will clear the doubts about the topic
