-A certain radioactive isotope has a half-life of 2 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?
A) Arithmetic in the first; geometric in the second
B) Geometric in the first; arithmetic in the second
C) Arithmetic in the first; arithmetic in the second
D) Geometric in the first; geometric in the second

The first column (time in days) increases by a constant amount (2 days for each half-life period), which is characteristic of an arithmetic sequence. The second column (mass remaining) is halved at each step, which is characteristic of a geometric sequence.
