X981: For Loop Multiples
Finish the for loop below. This method should return a string
containing the first n multiples of 3 concatenated together.
use a loop index that starts at 3, and add 3 to it each time
the loop repeats using the for loop's update step.
For example, multiplesOf3(3) returns the string "369",
and multiplesOf3(5) returns the string "3691215".
