A certain radioactive isotope has a half life of 11 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 item (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
