The series lx has been constructed, and from that series others are deduced to complete the Life Table, consisting now of six columns.
(1.) dx =lx −lx+1 =number of deaths in the year of age following, out of lx alive at the age x. By taking x successively at 0, 1, 2, 3…to the last age in the Table, the numbers dying in every year of age are obtained.
