Question 1134912: .
A certain radioactive isotope has a half-life of 5 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?

    days | grams
  -------+-------
      0  |  32
      5  |  16  (1 half life)
     10  |   8  (2 half lives)
     15  |   4  (3 half lives)
     20  |   2  (4 half lives)
     25  |   1  (5 half lives)

The first column is arithmetic; first term 0 and common difference 5

The second column is geometric; first term 32 and common ratio 1/2
