17. A technologist made a three-fold serial dilution of serum. Tube #1 had a 1/6 dilution of the serum, tube #2 had a 1/3 dilution of the serum and so on. Each tube was tested for the presence of an antibody. The last tube to show a positive reaction for the antibody was tube # 5. What was the titer of the antibody?
