Seven test tubes were prepared as follows:
Tube 1: 5 mL of NaOH and 5 mL of water
and tubes 2 - 7 were filled with 9 mL of water
One mL of tube 1 was then poured into tube 2; 1 mL of tube 2 was poured into tube 3; 1 mL of tube 3 was poured into tube 4; 1 mL of tube 4 was poured into tube 5;1 mL of tube 5 was poured into tube 6 and 1 mL of tube 6 was poured into tube 7.

This problem is almost exactly like the last problem you posted with the H+ concentrations and the pH. The concentrations will all be the same except ...
This solution explains how to calculate the concentration of OH- and pH of basic solutions in test tubes after several dilutions.
