To investigate the self-study time of high school students during winter vacation, a school uses systematic sampling to survey 50 students from a total of 900 students in grade 12. The students are numbered from 1 to 900. The interval number is calculated as $k = \frac{900}{50} = 18$. This means that every 18th student is selected. If the student selected from the first group (students numbered 1 to 18) has a number of 6, what should be the number of the student selected from the group of students numbered 37 to 54?
