A string’s nth mode has n+1 nodes and n antinodes
Evidence
It can be seen in Figure 4.6 that the first mode has two displacement nodes (at the ends of the string) and one displacement antinode (in the center). The sixth mode has seven displacement nodes and six displacement antinodes. In general, a particular mode (n) of a string fixed at both ends has (n + 1) displacement nodes and (n) displacement antinodes. — David M. Howard, Jamie Angus, Acoustics and Psychoacoustics, 1081
