A certain radioactive isotope has a half-life of 15 days. If one is to make a table showing the half-life decay of a sample of this isotope from 32 grams to 1 gram; list the time (in days, starting with t = 0) in the first column and the mass remaining (in grams) in the second column, which type of sequence is used in the first column and which type of sequence is used in the second column?

Is this right?:

in 15 days you have half of 32 which is 16
in another 15 days you have half of 16, namely 8
in another 15 days you have half of 8, i.e. 4
in another 15 days... 2 and finally in 15 more days you have 1

32, 32×1/2, 32×(1/2)2,...
