This table lists the consecutive notes from middle C to the next C note. This scale is called a chromatic scale and it increases in 12 steps, called half-tones. The frequencies measured in cycles per second, or hertz (Hz), associated with the consecutive notes form a geometric sequence, in which the frequency of the last C note is double the frequency of the first C note.
a. Find a function that will generate the frequencies.
b. Fill in the missing table values.
